Practical 3D prints: Increasing workshop storage with bolt-in brackets
Welcome back to our series on practical prints for your 3D printer. While many love 3D printing because it lets them make really cool props and miniatures, 3D printing has many practical applications. I use 3D printing to solve problems and to fix things. Although I admire the artistic creations folks make with 3D printers, I don't even own model paints.

The problem we're solving
A good place to start is a problem statement. What exactly do you need your 3D print to accomplish? In the case of the project shown in the attached video, I wanted to increase my workshop storage. Here's some background.
Also: ZDNet's DIY-IT 3D Printing and Desktop Fabrication Discovery series
I have four metal shelving units here in the workshop, and I've had them for something like 20 years. Recently, I had a welder add wheels to them so that they can move around, and that's proven to be incredibly useful. Unfortunately, individual shelves are pretty far apart, which leaves a lot of space unused. There's a lot of dead space where I could very much use some more storage.
I decided I was going to 3D print supporting brackets for four plywood shelves to make it happen.
Also: Everything you need to know about 3D printing and its impact on your business
Designing in TinkerCAD
In the attached video, I show how I built these little support units in TinkerCAD and 3D printed them, and how they will support three-quarter-inch plywood shelves and give me more shelf space.
The unique design feature for this build is the captive nut built into the support bracket. Each bracket bolts onto the metal riser supports. Inside the bracket is a channel where a nut slides in. That nut is called a "captive" nut because once it slides in, it can't spin. That makes it easy to tighten the bolt on the outside of the shelf support.
I used TinkerCAD to design this up. TinkerCAD has its limits, but it's very easy to use and for simple designs, very fast to work with. The key feature I used to create the captive nut channel and the tunnel for the bolt is called a "hole" in TinkerCAD parlance.
Any TinkerCAD object (either a basic object or a group) can be turned into a hole. In fact, a click of a button switches an object from a solid to a hole and back again. The hole is, essentially, negative space. If you intersect a solid with a hole and then group them, the area of the hole is subtracted from the solid space.
I first created a negative spatial representation of the nut by sizing a polygon to a size a bit larger than my real-world nut.
I made it a bit larger to allow the nut to slide in the channel easily. As the attached video shows, by duplicating the negative space nut (the "nut hole," if you will), I was able to create a channel that allowed the physical nut to slide into the middle of the bracket.
I used a cylinder turned into a hole to cut out the tunnel where the bolt slides into the bracket.
I also needed to create a rounded corner to my bracket, so it would fit in the rolled steel elbow of the shelf uprights. While most 3D modeling tools have a fillet tool, which takes an edge and rounds it over, TinkerCAD does not. While this annoys me to no end, sometimes you have to work around the problem.
As the attached video shows, I made my own rounded corner by creating a cylinder and grouping it with some rectangles, making up a new solid object that has a hard-won fillet on one side.
As it turns out, I wound up creating both left and right brackets, to accommodate attaching them to left and right uprights.
I also made some brackets slightly taller, so they would push the shelf up high enough to provide space for some bins I have.
Printing the brackets and building the shelves
To hold four new shelves I made a total of 16 of these brackets. Eight of them were left side brackets and eight of them were right side brackets.
I bought a 4 foot by 4-foot sheet of 3/4 inch plywood. There's a short but exciting montage of me using power tools to cut the plywood into shelves. While you've seen me use the miter saw and the sander before, this is the first time you've seen me use my new table saw.
I had to wait three months to get it this summer because it seems table saws are hard to get in the pandemic. I guess a lot of people are working at home and fixing things up, and also contractors are being invited inside a lot less, so many more of us are doing our own home fixes without outside help.
And, with that, I've just added another 18 square feet of storage into the workshop.
That'll make a big difference.
This project demonstrates how you can combine 3D printing and some basic woodworking to optimize your storage in new and helpful ways. Stay tuned for more practical prints.

Aircraft 3D printing: An engineer's story Boeing
Each Boeing 787 passenger aircraft has about 30 3D printed parts. Combined, Boeing Commercial Airplanes (jet airliners and business jets) contain 25,000 printed parts. And military aircraft F-15 and F / A-18 - about 40,000. Most of the components are components of air ducts, but there are engine parts and parts of the interior of the cabins.
Boeing spokesman Bernardo Malfitano spoke at the EAA AirVenture Oshkosh Aviation Enthusiast Forum and talked about how 3D printing is being used in the aircraft industry today.
Mechanic, test engineer, aircraft builder and pilot
Bernardo Malfitano has been with Boeing since 2007. In his career, he was engaged in the repair and maintenance of the air fleet, analyzed the wear and tear of aircraft.
Now he is involved in the development of new aircraft.
According to the expert, all popular 3D printing methods are now used in the aerospace industry: laser stereolithography (SLA), deposition method (FDM), selective laser sintering (SLS) and direct metal deposition (DMD). Unlike traditional techniques, in which the cost of a part depends on the circulation (the higher it is, the lower the price for each spare part), 3D printed products cost the same: it doesn’t matter if you ordered 10 or 1000 pieces. Therefore, it is advantageous to use this technology for small circulations.
Where are printed parts on airplanes?
Air ducts are the part of the aircraft where 3D printed parts are most widely used today. In modern aircraft, circulating air maintains a comfortable temperature for a person and a safe pressure. 3D printed air duct connections are used in the Boeing 787, F/A-18 and F-35 fighter jets, and Bell 429 helicopters.
There are also 3D printed parts in the systems that propel the aircraft. As a rule, these are metal products made by laser sintering or metal deposition. So, in the Boeing 777, the compressor is connected to the temperature sensor using a 3D-printed adapter. And in the F-15K Slam Eagle military aircraft, casings for turbines were made using volumetric printing. This reduced the cost of the part from $34,000 to $2,550 and halved its production time.
Interior details . Shelves, brackets and various fixtures in passenger aircraft cabins are often printed in plastic. For example, the popular Boeing A350 has over 500 of these parts on board.
Small parts. End caps, parts of seats and instrument cases - all this can also be made using the 3D printing method. In the Boeing A300 passenger ship, brackets and seat belt buckles for crew seats are produced in this way.
Advantages of 3D printing for aircraft construction
Additive technologies attract aircraft designers not only because they are economical.
They make it possible to optimize the shape at the model stage and significantly reduce the weight of the product. So, by replacing the cast metal bracket with a plastic one printed on a 3D printer, the designers managed to reduce its weight from 918 grams to 326. Of course, there is more than one bracket on the plane, so the total gain in weight is several kilograms. For passenger aircraft, lightening the design means reducing fuel consumption, which reduces not only the costs of the airline, but also environmental damage.
Parts with mesh and honeycomb structure are lighter than monolithic ones, but at the same time they do not lose strength. Each new sample introduced in the aircraft industry undergoes multi-stage tests, especially if it is a functional part.
Is it possible to print the entire aircraft?
If additive technologies are so good for 3D printing, is it possible to print an entire airplane? Bernardo Malfitano is sure that now it is impossible.
Today, 3D printing is successfully used to make drone bodies and working models of aircraft. At the Berlin Air Show in 2016, visitors saw the Airbus Thor, a remote-controlled aircraft about 2 meters long. All of its parts were 3D printed.
But to create the hulls of large aircraft - passenger liners, cargo planes, fighter jets - modern 3D printing technologies are not reliable enough.
Malfitano explained that the US has statutory manufacturing standards. The aircraft industry is governed by 14 CFR Part 25 (“Airworthiness Standards: Transport Category Aircraft”). It says that the structure of the materials must be strong, and the details must be reliable, which must be confirmed by certain tests. Meanwhile, testing parts created by 3D printing often reveals defects and inhomogeneities.
The second factor is the price. Aircraft manufacturing is mass production, so it is now more profitable to use traditional techniques at most nodes.
