How to make a 3d scanner

BQ formed the foundations of the DIY 3D scanner kit, and remains one of the best DIY 3D scanner on tight budget options. Then back in 2015, CowTech Engineering used the foundations led by BQ, putting their unique spin on an updated model.

True to the open source movement, Cowtech started a Kickstarter campaign to raise money to put their version of the original, the CowTech Ciclop, into production. The team set the lofty goal to raise $10,000, and were met with surprise when the community rallies to raise $183,000. The CowTech Ciclop DIY 3D scanner kit was born.

So what are the differences between CowTech’s version and BQ’s DIY 3D scanner?

The CowTech Ciclop still uses the Horus 3D software program as it does a fantastic shop for 3D scanning objects. Differences however include a slightly different design, which the team spent days designing so that the parts could be 3D printed on any FDM 3D printer. Some desktop 3D printers only have a small build volume, so CowTech designed parts that can be printed on any printer with a build volume of 115 x 110 x 65 mm, which almost all 3D printers have.

Additionally, CowTech’s Ciclop has adjustable laser holders, and whereas the BQ Ciclop uses threaded rods, CowTech’s DIY 3D scanner uses laser-cut acrylic. This isn’t anything drastic and the scanners still look fairly similar, but CowTech only intended to improve the existing design, not reform it. CowTech sell the Ciclop, ready-to-scan, for $159 on their website. Overall, this is a great cheap DIY 3D scanner, and very effective for laser triangulation 3D scanning.

OpenScan Classic and OpenScan Mini

• Max Scan Volume: 180 x 180 x 180 mm / 80 x 80 x 80 mm
• Accuracy: Up to 50 microns
• DIY 3D scanner technology: Photogrammetry
• Price: Starting at $100.00 up to $200.00 for a complete kit with 3D printed parts and electronic

The Mini and Classic are two low-cost but high-quality 3D printed DIY scanner projects designed by German company OpenScan. In action, the OpenScan uses a stepper motor mounted to a 3D printed frame to rotate an object to capture images from various angles. These are then compiled into a high-quality 3D model using open-source software or OpenScanCloud, ready for 3D printing.

Where the OpenScan Classic and Mini differ from one another is max scan volume and camera/SBC options. The Mini features an 80 x 80 x 80 mm scan volume, while the Classic more than doubles the scan volume to a roomy 180 x 180 x 180 mm, perfect for scanning larger objects. The Openscan Mini – the cheaper and smaller 3D printable 3D scanner.

The OpenScan Mini is tied to a Raspberry Pi and only works with either a Pi Camera or Arducam IMX 519 and includes one-click easy scanning. This allows the completed scanner to rotate not just the object but also the camera for a more detailed point cloud. 

On the other hand, the OpenScan Classic is also compatible with Smartphones and DSLR cameras, which generally means better quality photos and, as a result, higher-quality models. It’s the tinkerer’s option and better suited for those that want to customize the scanner to their needs.

OpenScan offers a solution for all DIY skill levels and budgets, whichever model you decide on. You can customize kits based on your needs or order a complete kit that includes all the electronics and 3D printed parts.

AAScan Open Source 3D Scanner Based on Arduino and Android

AAScan is a very recent (February 2020) DIY open source 3D scanner that’s fully automated in taking photos and moving the object around on the scan plate. All the files are on Thingiverse, which we’ve linked below. Interestingly, the creator stresses that the AAScan is intended to be a purposefully minimalist machine, able to scan but not filled with extra features beyond this primary capacity.

All the instructions for how to build, print and assemble the AAScan are on the Thingiverse page, requiring an Arduino, some electronics, and either a 3D printer to print the plastic parts or someone else to print them for you — such as from a 3D printing service.

You can view the DIY scanner on Thingiverse here.

FabScan Pi

• DIY 3D scanner technology: laser triangulation
• Price: $100-200 depending on which version

The original FabScan was a DIY 3D scanner built by Francis Engelmann as part of his Bachelor’s thesis back in 2010. Since then, there have been numerous improvements made in new iterations up to the newest model, the FabScan Pi. This new model uses a Raspberry Pi camera along with the new design to offer higher quality 3D scans.

Based on laser triangulation technology, the FabScan Pi is one of the best DIY 3D scanner options for those who are into doing it themselves. Depending on if you go for one of the older models or the latest, the price can vary between $100 and around $200 to completely create the 3D scanner. Overall, it’s a really cool kit and thesis which you can make at home.

If you want to create your own FabScan, you can follow the assembly guide here.

DIY Standalone 3D Scanner by Jun Takeda

• DIY 3D scanner technology: Photogrammetry
• Price: $200.00

The DIY Standalone 3D Scanner is an excellent option for those that want a hands-on project that results in a reasonably accurate and easy-to-use stationary 3D scanner. 

By combining a Mbed board with a camera and OpenCV libraries, the scanning process is largely automated with just a single button push. The scanner captures multiple images of an object to create a 3D model that’s then output as an STL file written to an SD Card.

To complete the project, you’ll need a GR-LYCHEE as a centerpiece sided by smaller electronic parts, plastic sheets to create the housing, and various nuts and wiring to piece it all together. 

As the name implies, it’s very much a DIY project and, as such, would best suit those happy to troubleshoot any potential hurdles with little hand-holding. Though there are instructions, you’re responsible for designing the housing, wiring the board, and calibrating the camera.

Arduino-Controlled Photogrammetry 3D Scanner by Brian Brocken

• DIY 3D scanner technology: Photogrammetry
• Price: ~$100

The Arduino-Controlled Photogrammetry 3D Scanner is a 3D printable 3D scanner DIY project that leverages the camera on any run-of-the-mill Smartphone and a cheap Arduino UNO SBC to keep costs low.

The core idea is to assemble a turntable consisting of 3D printed mechanical parts, including a print-in-place bearing. A Bluetooth-connected Smartphone does the actual scanning via the normal photogrammetry process. As for electronic components, you’ll need a servo motor, LCD screen, Arduino Uno, PCB, stepper motor, Bluetooth remote, regulator, and a small joystick module.

Once assembled, the Arduino-Controlled Photogrammetry 3D Scanner can capture anywhere from 2 to 200 photos in a single 360° rotation for reasonably detailed scans. The images are then sent to photogrammetry software such as AutoDesk Recap Photo to assemble a 3D model.

Aside from the cost of filament, expect to pay no more than $100 for all the parts and the STL files to 3D print the turntable.

Semi-assembled DIY scanners

Revopoint POP / POP 2

• Price: $500-700 — Available at Revopoint store here
• Accuracy: 0.3 mm
• Max Scan Volume: 200 x 300 x 300 mm
• Scan Speed: Up to 8 FPS
• DIY 3D scanner technology: Structured light

Though not technically a DIY scanner, we thought we’d slide in the Revopoint POP as a cheat option for those that want to save time and want largely better quality scans than you’d get with a homemade alternative.

It comes semi-assembled – you just need to attach the tripod, connect the USB and the turntable, add the sticker markers for better scan tracking, and optionally build and attach the larger turntable – so you can get started in just 5 minutes!

The catch? At around $500, the Revopoint POP is considerably pricier than a DIY scanner. Still, it may be worth paying the premium for the convenience and reliability.

The Revopoint POP offers 0.3 mm accuracy (the POP 2 offers within 0.1 mm!) and automatic alignment technology, making for more detailed and smooth full-color 3D models than DIY scanners. It can capture 360° scans of objects up to 200 x 300 x 300 mm, besting most DIY options.

The main benefit of all this is high accuracy scans that are just about ready for 3D printing with very little post-processing needed to iron out imperfections and poor surface details.

Ease of use also extends to the intuitive software, which works with Smartphones for on-the-go scanning and features exports to STL and OBJ formats. Alongside, it bundles in best-of both-worlds handheld and stationary modes. Five different scanning profiles allow you to tune the POP to each scan with face, body, feature, mark, and dark mode.

Which is the Best DIY 3D Scanner?

This depends on how much DIY you want to take on yourself, and how much you are ready to spend.

One of the most cost-effective options is scanners based on the Ciclop open-source 3D scanner design. You can purchase a low-cost Ciclop scanner like the BQ Ciclop or CowTech Ciclop 3D scanner, then 3D print the parts from home and modify and tune the scanner to your liking.

Alternatively, the Revopoint POP is an excellent semi-assembled 3D scanner with great specifications and software at an affordable price for those that want to save time.

What is a DIY 3D Scanner?

A DIY 3D scanner is a cost-effective, home-made device constructed from manufactured or 3D printed parts designed to capture the characteristics of a specific object – such as size, surface details, and shape – by scanning it from multiple angles to create an equivalent point cloud that can be processed into a 3D model via software.

Almost DIY 3d scanner for home / Sudo Null IT News scanning is out of the question.

But the main plus that I took out from the article is the David-3D scanning program, which really has a good manual in Russian and, importantly, buying a license is the last thing required, since the free version is limited only to saving the scan result. Everything else works in full, which means that it is quite possible to test the program, settings and your hardware as much as you like. And if you don’t need the result with high accuracy, then you can do without buying a license at all.

I needed accuracy, since the main thing I wanted to scan was miniatures from the Warhammer board game (so that later I could change them as I wanted and print them :)). The height of these "soldiers" is only 3 cm, but this does not prevent them from being very detailed.

If you do not need to shoot such small objects, then your equipment requirements will be lower, which means that it will be much easier to assemble a similar scanner for yourself.

The principle of the program, and accordingly scanning, is well described in the article, which was linked above (I think it is not necessary to duplicate this). It is advisable to read that article first, as this one will be in some way its logical continuation.

But let's start in order. What you need to try 3D scanning at home:
1 - projector.
2 - webcam.

That's all, the short list turned out surprisingly well. However, if you want to get very accurate and high-quality scans, then you will have to modify some things with pens. Of course, you can’t do without additional costs, but in the end it will still cost less than buying any of the commercially available 3D scanners, and the quality of the result can be obtained much better.

Now, in order and in detail.

PROJECTOR.

I, like the author of the previous article, started my first experiments on scanning with a laser pointer, but they immediately showed how inconvenient this method is. There are several disadvantages here at once:
- the impossibility of obtaining a beam with a sufficiently thin line. Moreover, when you turn the pointer, the distance from the lens to the object changes, which means the focus is lost.
- if you need to scan regularly, turn the laser pointer with sufficient accuracy and smoothness by hand is very difficult, and tiringly easy - the hands are not such a stable tool when it comes to a long time.
- you have to scan in the dark so that only the laser line is visible and nothing more.

And if the second drawback can still be dealt with by creating a special rotary mechanism (although this is already not such an easy task, in any case, this cannot be done in 5 minutes on the knee), then getting rid of the first drawback is more expensive.

When I realized all this, I decided to try scanning with a projector, for which I borrowed some simple model from a friend.

A small clarification should be made here - in the last article, the author mentioned the possibility of scanning using a projector, although the proposal was, in my opinion, very strange -

A projector with a powerful lamp is suitable, the light of which must be directed through a narrow slit to the object being scanned

This may have been the only option in earlier versions of the program, but in version 3 that I experimented with, the projector was used much better, because there's a feature called Structured Light Scanning (SLS). Unlike laser scanning, the projector immediately projects a grid of vertical and horizontal lines of various thicknesses onto the object, which reduces the scanning time by an order of magnitude and allows you to automatically shoot the color texture of the object. Well, with good focus, a 1 pixel wide line is much thinner than you can get from an inexpensive laser pointer.

Unfortunately, I didn’t take pictures from those first experiments, and there wasn’t much to take pictures of - the projector is on the table, next to it is a webcam, all of this looks in one direction :) However, even such a simple design showed that this option much better both in terms of scanning speed and quality. Then I decided to buy myself a projector for these purposes.

The criteria for choosing a projector were simple - higher resolution, lower price and dimensions :)
The choice settled on IconBit Tbright x100 - an ultra-compact DLP LED projector, 1080 resolution - at that time it seemed to me that you couldn’t imagine better, but as it turned out later, I was wrong, although while working with it, I got a lot of interesting experience.

The first problem that occurs when scanning a small object with a projector is that for best results, the size of the projected grid should roughly match the size of the object being scanned. This projector made it possible to obtain the smallest screen diagonal at the closest focus - about 22 cm. Agree that against such a background, a miniature 3 cm high is far from the concept of "approximately equal sizes." The answer was found on the official forum - people in such cases install camera lenses on the projector for macro photography. Given the small size of the projector lens, I opted for marumi lenses with a thread diameter of 34mm.

Using two of these kits, I managed to get a projector screen with a diagonal of only about 3 cm. Which turned out to be quite enough to make my first microscan -

This is a single scan, therefore there are “holes” on the model, torn edges and etc. By turning the coin and scanning from different angles, you can get several of these scans, which are subsequently combined into one object (the scanning program itself allows you to correctly combine different scans, stitch them together and save them as a single object). In the process of stitching, the shape of the object is also specified. But saving the results of such stitching is possible only after purchasing a license.

And now the moment has come for the first thing that is not necessary for scanning, but with it the process is much more convenient - this is a stand for a projector with a camera. The calibration process itself is needed not only for the program to recognize the parameters of the equipment - the software must also calculate the relative position of the camera and the projector. In the course of work, their change is not allowed (as well as changing the focus of the camera), which means that it is necessary to firmly fix all this, because the number of scans can be large even for one object.

David's main page shows a similar system - it is nothing complicated. Yes, and looking through the forum and seeing how different people organize it for themselves, I realized that nothing complicated is required here.

For these purposes, a stand was taken from a burned-out LCD monitor, and plexiglass from it, cut and glued like this design, as it looked in the first version , which allowed changing the screen diagonal and scanning objects of different sizes.
It should also be mentioned that scanning with a projector does not require the constant presence of calibration panels in the field of view. After the calibration is done, they can be removed. This allows, having calibrated the installation, to easily transfer it, move it, etc.
That is, you can use a large calibration template to calibrate at home on the walls, and then go outside with this stand and laptop and scan your car, for example. We took a smaller template, put a couple of lenses - and you can scan jewelry.

Recently, the company has released an improved scanning kit, here the stand looks much more serious and interesting -

2000 euros is not entirely justified, it is not difficult to assemble something like this yourself and much cheaper.

Let's go back to the projector. As it turned out, this projector had one major disadvantage for being used in a scanner, namely its native resolution (854*480). And everything would be fine if it produced the same output, but alas, the picture was converted to standard resolutions (such as 1024 * 768), and as a result, a line one pixel wide was somewhere brighter in different parts of the screen, where - something dimmer, somewhere already and somewhere wider . .. All this had a negative effect on the quality of scanning, expressed in the form of ripples and stripes on the resulting model.
By that time, I was already thinking about buying a projector for a stereolithographic 3D printer (http://geektimes.ru/post/245590/). After considering several options, I settled on the Acer P1500 model, because. it does not need any modifications to be used in a printer (this projector, without any lenses, is able to give a focused image on a screen of about 4 * 7 cm). So, for the scanner, it will fit perfectly. At the same time, the resolution of 1920 * 1080 is real. And so it happened, I still use this projector and am completely satisfied with the results.

CAMERA.

The criteria for choosing a camera were the same as when choosing a projector. Having gone shopping, I stopped at the Logitech C615. The scan of the coin was made from it, without any modifications. But when I tried to scan the figurine, I ran into a problem called "depth of field". When the object is so small, then in fact we get macro photography, and sharpness with such shooting is achieved only in a small segment, literally just a couple of millimeters (which is why the coin was scanned well - the relief fit perfectly into the sharpness area). It was decided to convert the camera to a different lens. Several different lenses were ordered on Ebay for testing, and a new case was cut out for the camera board. The plan was like this0003

The final result was slightly different

The main idea, I think, is clear. And now, both on Thingiverse and on the forum of the program, you can download stl for printing cases for different types of webcams.

I had to remove the standard lens from the camera board, and as it turned out later, the IR filter was removed along with it, so be careful in this matter. The filter will then come in handy for use with other lenses, although you can buy them separately - the price is cheap.

Thus, I have formed such a collection of lenses.

While I was waiting for the lenses to arrive, I was reading various photography forums. Studying the issue with depth of field, I found out that you can increase it by closing the lens aperture more. This means that the lens was required one in which it was possible to adjust the aperture (alas, among those ordered, not everyone had such an opportunity, but luckily I got a couple of them). In general, to improve the camera, it is desirable to have a varifocal lens with a zoom and an adjustable aperture. In practice, everything turned out the way it was in theory - closing the aperture, an increase in the depth of field was immediately visible, which made it possible to scan three-dimensional, but small objects.

The main lens I use is mounted on the camera in the photo above. The second, with an adjustable aperture, is the largest, in the center. I use it for very very small objects. The rest are without a diaphragm, so I don’t use them - it turned out that these two were quite enough.

Now I plan to either find a webcam with a higher resolution (the quality and detail of the scans directly depends on the resolution of the camera), or try to use some digital camera for this purpose with the ability to shoot video - usually you can get a lot more resolution in them, and lenses are better.

Actually, this could be the end - it seems that he told about everything. I also thought that this was the end of my scanner assembly, but the farther into the forest ... While studying the forum of this program, I often came across various schemes of turntables - fortunately, the software allows you to automate the scanning process. After one scan, a command is sent to the com port, the turntable rotates, turning the object by a given number of degrees, and gives a command to the next scan. As a result, with one click of the mouse, we have circular scans of the object - it would seem, what more could you want? I tried this system with interest, but alas, I absolutely did not like this approach, and there are a couple of reasons for this.

1 – if the object has a complex shape, then simply rotating it will not be enough – you also need to tilt it in different directions so that the camera with the projector reaches all the depressions and other hard-to-reach places.
2 - even if there are no such places, and considering all the scans that were made, there are no parts left on the object that did not fall into the scan, the question of the accuracy of the scan remains.

Let's say that some part of the model on one of the scans came out perfectly. But this does not mean that on all the scans in which this part fell, it also looks perfect, and when stitching scans from different angles, the result will be averaged, which cannot please. The program allows you to slightly edit the received scans (you can cut out the unnecessary part). If we rotate the model by 20 degrees, then after a full rotation we will have 18 scans, the part we need may well be present on half of them, therefore, in order to leave the best result, we will need to remove this piece from 8 scans . .. And such pieces with a complex There can be many models, as a result, almost half will be cut off from each scan, which is very laborious and time consuming.

Instead, it is better to immediately scan adjacent areas after the first scan and check the result. As soon as a piece is ready, we move on to scanning the next one, and so on, until the entire model is in perfect shape. This approach gives the best results in less time.

But the question of convenience arises. Agree, it’s inconvenient to manually try to rotate an object, looking not at it, but at the monitor - in order to control the hit on the lens without changing the distance to the camera and the projector at the same time (so as not to lose focus). With the next similar balancing act, I accidentally touched the camera, which accordingly knocked down the entire calibration, and the whole process had to be started anew. I categorically did not like this alignment, and after some thought I came up with a plan for such a design (which, as you understand, I subsequently assembled).

This is not a turntable in the usual sense of the term. Thanks to this design, I can not only rotate the model, but also tilt it as I need. In this case, the center of the model remains in the plane of focus, but even if not, you can move the mount with the model back and forth.

All this was assembled on arduino, a small control program was written, and as a result, now I don’t have to get up from the computer when scanning - using the program, I change the position of the object being scanned, and at the same time, right there, in the window cameras I choose the best angle for scanning.

Insides

I put the possibility of automatic scanning into the program, as well as scanning not only in a circle, but with inclinations of 45 degrees in one direction and the other, which gives three times more scans. Nevertheless, in the end, I still never use this opportunity - it's too inconvenient to sort through the resulting pile of scans and clean them from unsuccessful pieces.

We should also mention some nuances of scanning.
1 - it is impossible to scan shiny and mirror surfaces. The light from them is reflected, or gives such a glare that the program cannot correctly recognize the line. If there is a need to scan such an object, then such parts will have to be masked with something (washable paint, paper tape, etc.).
2 - it is more convenient to scan monotonous objects, since when the camera is set to a light color, the projector's brightness is not so high, the exposure is low, etc. And a dark-colored object needs more brightness, so if you have a multi-colored object, then different parts of it require different settings to get the best result. Here, too, it is more convenient to use scanning the object in parts.
3 - if you want to immediately get a color texture, then please note that the settings of the camera and the projector for scanning do not affect the settings for removing the texture (the scan is generally done in black and white mode), so play around with the settings in the texture mode just as you would do in scan mode.

My scanning process now looks like this:
- Focusing the projector and camera

The projector's light is too bright and the projected grid is not visible in the photo, but here is the view from the camera in the program

- scanner calibration

printed on magnetic paper - so you can very quickly adjust to different sizes of scanned objects.

Software view

It is recommended that the combined angle between the beam of the projector and the camera be around 20 degrees. Therefore, such a stand is used - when scanning large objects (for example, a person), the camera should be set aside much further from the projector, but here they are close to me. The location of the camera relative to the projector can be only vertical, or only horizontal, depending on the geometry of the object. In this case, the arrangement is diagonal (13 degrees vertically and 36 degrees horizontally).

Scan results from different angles. These are already cleaned up scans, i.e. all unsuccessful and unnecessary parts (figure stand, mount that got into the frame) parts have been removed.

Combining scans for subsequent merging into one object

Due to the fact that each scan has its own color, it is convenient to control the correct alignment.

Well, after combining the scans from different angles, we get the following models

Miniature of Boromir from Lord of the Rings.

When scanning a multi-colored object, the result is slightly worse if you don't bother too much. But then you can get an object with a texture right away :) , even fingerprints people scan. And there are even scans of the same miniatures from Warhammer

In conclusion, I would like to say that no matter what hardware you use, no matter what expensive 3D scanner you buy, this is not a panacea for printing anything. Theoretically, of course, you can send the resulting object to the slicer and print, but there are several reasons why you should not do this, but in any case, you should study 3D graphics packages.

1 - The resulting scans, with good scan quality (and we want to get the best quality) have a lot of polygons. No, even is VERY a lot. The scan of Boromir after the merger contained more than 8 million polygons - not every slicer will be able to work with such an object.
2 - Any objects bear traces of assembly and manufacture. And if in reality needle files and sandpaper are used to fix this (and sometimes there are still inaccessible places where it is impossible to use tools), then working with a digital copy of an object, we can change it as we like - remove defects, improve detail, etc. .
3 - As I said at the beginning of the article, when I thought about the scanner, I did not want to print copies of objects, but change them as I please. I am not a sculptor, I do not have the tools, materials and skills to sculpt such a small model. But knowing how to work in 3D, it is much easier for me to scan a similar Boromir and make him some kind of Prince of Denmark.

By the way, this model already contains almost 100 times fewer polygons than the scan result.

DIY handheld laser scanner, assemble the body!

Hello everyone!

A handheld laser scanner has always been a dream. But for a long time I could not even imagine that I would get my hands on something like Creaform HandySCAN or Shining Einscan...

Suddenly, a few months ago, a proposal from the Russian company Volume Technologies appeared for self-assembly of a laser handheld scanner according to a finished project. This is a company widely known in narrow circles that makes Range Vision level scanners, but operates according to a different business model, more than 10 years of experience in the development of 3D scanning technologies and the production of modern equipment based on them for use in production, in professional activities in the field of education.

https://volumetechnologies.ru/vt_laser

As I build the scanner, I will share my thoughts, suggestions and additions.

Assembling the Case.

The project contains both ready-made gcode for printing on Picaso and Anycubic Viper (04 nozzle, PETG, suitable for all Ender 3 clones with a bowden extruder) and separate STL for printing on any printer.

Prepared GCODE allows you to get the desired print without much trouble.

The project also contains useful recommendations regarding 3D printing of parts.

The body of the scanner is printed from black PET-G plastic on an FDM printer, nozzle 0.3 or 0.4 mm, layer 0.2 mm. The first layer is a PrusiaSlicer Hilbert Fill Curve which, when printed on glass, produces a very high quality glossy surface. Before printing on glass, a layer of 3d glue is applied on a cold, folded non-woven cloth in one pass. After the glue spreads and dries, with the formation of a thin glossy film, the table is turned on for heating and printing starts. After printing, the parts are washed from 3d glue in water. The buttons are printed with a change of material - the bottom is made of transparent PET-G, the top is made of black PET-G. The insert between the buttons is made of transparent PET-G. The inscriptions on the case are applied by laser engraving, on our plastic we get even white letters on a black background.

It was interesting to read about the Gilbert curve) But I print on several printers with a 06 nozzle in Kure, it didn’t work out to make friends with Pryuschaslicer, so we use what we have.

In the folders for picaso there is both a layout in the chicken parts, from where you can understand how much and what you need to print, as well as individual parts and Gcode.

In addition to all this, CAD files for the body are available, which can be used for printing if necessary.

I printed flat sidewall parts on ultrabase 02 layer. When printing, there are a lot of movements and retracts, I caught failures several times, the nozzle clogged. In general, I recommend lifting during retraction, temperature and airflow calibration, reasonable speeds.

Pen parts already come with pre-installed supports in the right places, the slicer will offer additional supports, we print without them.

Some of the parts need to be bent after printing to fit into the case. There are no recommendations in the instructions on this matter, but if you heat it up to 80-9 on the printer table0 degrees and bend, then my parts are bent in the center. In addition, the bending radius came out quite large. After several tests, among which were attempts to bend a cold product and the part simply burst, I came up with the following algorithm. The knife heats up, leans against the attachment point, and while the line is heated, the part bends along it by eye at 45 degrees. The angle turns out to be sharper, the plane does not bend. But based on the results of this work, I recommend printing the part from the CAD model already in the desired folded form or on FDM with supports or on a photopolymer printer.

Printing a mirror surface did not work) Therefore, I decided to experimentally blow out the case with liquid rubber.

I bought cheap tires and blew them out a few times. It turned out well. The surface is pleasant, matte, soft touch. Of the minuses, cheap liquid rubber is applied in a very thin layer, the cans were enough for literally several layers on the entire body. The scent is strong and takes a long time to dry. The next day, it still sticks to the hand.

Before assembling on self-tapping screws, we go through all the holes with a 2.4 mm drill, quickly assemble on black M2.6x12 screws for fitting

Case ready!

What's left?

A very simple project. Everything is as accessible as possible and prepared in advance. In the event of a breakdown, all parts can be replaced. Greater freedom for creativity and refinement of the case.

Not able or willing to print? - order ready! VT sells finished parts for a reasonable price.

In the future, if the body is modified, I would print the entire body on a medium format photopolymer type Mono X, all parts fit on the table, you can complicate the forms and make the design close to Creaform and Shining.
