Cool mechanical 3d prints

Why 3D print toys?

This is probably the first question that comes to mind, and it is not surprising, because often 3D printing can cost you more than the cost of such a toy in the store. But there are also a number of advantages of 3D printing, as well as cases when it would be more profitable and appropriate to turn to creating models on a 3D printer. nine0007

• As already mentioned, a toy printed on a 3D printer can be absolutely unique due to the ability to set exactly the shapes, sizes and colors that you and your child want.
• Some toys can be difficult to find in the store, and their cost may exceed the cost of their printed copy.
• Sometimes you only need to replace one or a few broken or missing parts of a toy, such as a building toy. In this case, it will be much more profitable and more expedient to use a 3d printer than to buy a whole set for a high price. nine0259
• An important factor is, of course, the impressions of the 3d printing process itself, which will captivate both a child and an adult. And the positive emotions of your child from the toy you created will be the best reward!
• And for those who are just getting acquainted with their printer and 3d printing in general, the process of creating toys will be an excellent, exciting simulator to improve their skills and gain experience.

Which toys can be 3D printed? nine0003

In the context of constant development and increase in the possibilities of 3D printing technology, you can create almost any toy on a 3D printer, but the result largely depends on the capabilities of your device, your abilities, as well as the time, resources and effort that you are willing to devote to this process. Therefore, more or less simple projects are most often created on a 3D printer. But the relative ease of manufacture does not mean boring finished products! Below we will give you a list of 20 interesting 3D printed toys that are not particularly difficult to create. Among these crafts you will find toys for children of all ages, including the smallest: mechanical products, motion figures, building blocks and even rattles! For each toy from the list, we leave a link to the finished model so that you can try them yourself. So let's get to know them better! nine0007

1. Mini monster truck

Not everyone can afford a monster truck, but if you have a 3D printer, you can print yourself a mini copy of it... which is almost as cool. Thanks to the all-printed suspension and removable discs that attach easily and without the aid of glue to the body, this truck is perfect straight from the printed surface.

You can even choose from a variety of body styles and wheels. And for a two-tone tire, stop printing the wheel at 19.8 mm and replace the filament.

2. Surprise eggs

Bigger isn't always better. And often the most interesting thing is just a small size, and these 3D printed eggs with a surprise are an example of this.

These tiny cars with moving wheels and other accessories are amazing! Plus, you have plenty to choose from, as you can print surprise eggs with just about anything inside, be it a fire truck or even a fighter plane! nine0007

Support not required for these models. We advise you to use at least 40% infill to make sure that small elements are both beautiful and durable. Given the number of such tiny parts these machines have, be prepared that printing them can be a real challenge for you, but with good calibration and fine tuning of your machine, everything will work out in the best way!

3. Elastic Gliders

Get ready to take off! Source: Thingiverse

With 3D printed gliders you will be able to “pull” even more fun out of regular rubber band ! Just 3 simple steps, and your glider will take off: hook it with an elastic band, pull it towards you and release it.

With this model on Thingiverse, you and your friends can take to the skies a whole flotilla of these rubber gliders!

100% infill and a layer height of 0.1 mm are recommended for greater aircraft strength and longer life for thin wings. nine0007

4. Folding sword

This toy may not be best given to a child when there are breakable items nearby. But in the right environment, telescopic swords will bring tons of fun and enjoyment to kids! From the designer of this folding pirate sword, you can also find models of telescopic katana, daggers and even lightsabers!

This Telescopic Pirate Sword is designed for printing at low speed using a 0.4mm nozzle. Also, successful printing requires a printer with a good retract and precise settings for Coast (turning off extrusion at the end of the layer print) and Wipe (“wiping” the nozzle at the end of the layer). nine0007

5. Micro Catapult

Hit all your enemies (or at least the roommates). Source: Thingiverse

This little catapult is a great toy for kids and bored office workers alike. She can throw small crumpled pieces of paper and any other small things that will fit in her. Selected ammunition can fly about 2 meters, which is enough to hit unsuspecting victims at another table! nine0007

This model is an all-printed prefabricated assembly that does not require any supports or special adjustments. A minimum filling and layer height of 0.25 mm is sufficient.

Despite the fact that many catapults are made from PLA plastic, the author of the design still insists that this model is not for PLA, but for ABS plastic. We can also recommend PETG filament for this printing, which has the best qualities of PLA and ABS.

6. Top

The oldest toy for the whole family. Source: Thingiverse

As far as we know, the spinning top is one of the oldest toys in the world. In ancient times, tops were made from almost any material: from stone and wood to fruits and nuts. And now additive technologies allow you to make your own spinning top using a 3D printer! All you have to do is print this model, glue the pieces together and have fun with this simple yet fun toy!

Offered 0.2 mm layer height and 20% infill.

7. Moving Animals

Making flexible prints on a 3D printer has become a completely affordable and common practice thanks to special filaments such as TPU. But what if we said that you don't have to use flexible plastics to create flex parts?

Using excellent hinges that are printed in one piece with the entire model, you can create movable flexing toys even from plastics such as PLA, ABS and PETG, without any additional settings and adjustments. nine0007

The standard specifies a layer height of 0.2 mm and an infill of at least 15%.

Most popular models:

• Octopus
• T-Rex
• Lizard

8. Spirograph

Convenient case for creativity at any time. Source: Thingiverse

Everyone knows the children's toy spirograph, which allows you to easily draw masterpieces with repeating geometric patterns. But this model has gone a little further and is a whole case containing a platform for drawing and a compartment for storing gears and paper. It fits easily into your pocket, backpack and bag, so you can take it with you and paint whenever you want! nine0007

The case has several levels. The lower level holds slips of paper for notes, drawing gears and, if desired, a small pencil or pen, if, of course, you can find one. The next level provides a secure, flat drawing surface so you can make art while walking! The top level has fixed gear teeth and holds the piece of paper in place.

A layer height of 0.2 mm and an infill of 20% or more is recommended. As a loop, a regular straightened 1.75 mm filament thread is used. nine0007

9. Transformers

Toys from the planet Cybertron. Source: Thingiverse

Transformers are still a hugely popular children's toy, so these Optimus Prime and Megatron are sure to please your kids.

This printed Optimus Prime transforms from a classic Optimus truck into a fully functional standing robot. And it's amazing, considering that you immediately get a ready-to-use all-printed model right from the printing platform, which does not even require supports! nine0007

But, of course, every Optimus needs an opponent to fight. Therefore, you can also print Megatron, but it should be noted that his model is more difficult to print and consists of two parts.

10. Set of toy tools

The first tools for little craftsmen. Source: Thingiverse

The toy tool set is a great way to introduce kids to basic tools, their appearance, purpose and how they work. Print your child's first hammer, screwdriver and pliers and he'll feel like a real craftsman! nine0007

The hammer is modeled to fit two pieces together with a screw, but some users simply glue them together, which is just as beautiful. You can also use a hammer to assemble pliers: just lay the two pieces on a flat surface with the screw down and tap lightly a couple of times.

Model can be found here.

11. Castle

Build your own medieval world! Source: Thingiverse

This medieval castle playset is meticulously designed for 3D printing. Walls and towers are easily attached to each other with a simple connection. You can make as many details as you want to create a large or small original castle layout of your own! The set contains walls, towers, houses, characters, animals and a variety of props to add to the fun of this medieval set. nine0007

All parts are small enough to be printed comfortably even on 3D printers with a small print area: 140x140x140mm. For such purposes, the Flashforge Creator Pro 2 3D printer is perfect, equipped with two independent extruders and has excellent printing accuracy. This printer will cope with the study of small details, and two extruders will help you print several parts at once or one part in two colors!

12. Lego bricks

Favorite construction set is now more accessible! Source: Pinterest

LEGO is one of the most popular toys for children. At the same time, the cubes of this designer are made of ordinary ABS plastic. So, having your own 3D printer, you can print the missing/lost Lego bricks yourself or even some of your author's design of the details of this amazing designer! At the same time, you can use not only ABS, but also other 3D plastics: PLA and PETG are also great.

Thingiverse has a lot of Lego models, and we'll take a look at one of them. It's customizable model of several different LEGO and LEGO DUPLO pieces. These bricks are not completely identical to real Lego, but they are compatible in every way.

13. Ballista

Introducing a fully printed ballista model, ready to use right out of the box. One has only to set the string and load the projectile, and this ballista will impress you with its simplicity and good range of the arrow. As a bowstring, you can use several layers of thread or ordinary stationery gum. nine0007

Recommended to print in PLA or PETG with 90% coverage and 0.2mm layer height.

14. Edible toys

The project was originally envisioned as a way to turn commonly discarded residual materials such as wood and cork into toys: helicopters, planes, cars and so on. But soon, wood and cork were replaced by more accessible and easily pierced materials: fruits and vegetables. With this project, you can turn ordinary food items into fun personalized toys. nine0007

15. Anti-stress keychain

Add some flair to your keychain with this cool little toy. She will entertain you wherever you are!

This model is not the easiest, but try it and you will definitely succeed! Important print quality settings are "Outer Walls Before Inner Walls" and being extra careful with temperature. It is printed with supports and requires a certain, sometimes lengthy, post-processing. Remove not only supports, but also make sure that the surface of the part is smooth, otherwise it will cling and stutter. A scalpel or a 1 mm drill will do. Periodically rotate the gears to see where it still sticks, which is especially true when using PLA. nine0007

16. Chunky Trucks set

Two models from the fun and cute Chunky Trucks set. Source: Thingiverse

The adorable Chunky Trucks collection includes various unique models of small trucks, fun builders and even a movable barrier. The cars are specially designed so that even the smallest children can play with them. Unlike builders, who are not recommended to be printed for toddlers so that they do not try to put them in their mouths, but which will greatly amuse older children. nine0007

All models can be printed without supports. And for long truck life, at least 25% infill and three-wall use are recommended.

17. Rattleswords

Arm your warrior! Source: Thingiverse

Rattles are an integral part of all babies. But what if we move away from banal and boring designs and build a rattle in the form of a sword for your little warrior? This fun design will not only amuse your baby, but also you, as this rattle will be a lot of fun to print! nine0007

All corners of the model are rounded for safety. There are also two versions of the tip. Initially, a gem was attached to the tip, but after some concern that the stone could slip off the tip and be swallowed by a child, a second version was created that did not include a gem.

Print two sets of dots first. Then, while printing the sword, throw them inside the blade. This will ensure that the peas stay inside the rattle forever. After printing all the elements, simply fasten them with superglue. nine0007

As with any printed toy, parental guidance is required. Be sure to throw away the toy if it breaks.

18. Viking Squigglepeeps

Squigglepeeps is another baby-safe toy, this time with absolutely no glue required. These fun chubby Vikings and their boat are too big to choke on, making them suitable for kids of all ages. They look funny even in one color, but they will be even more beautiful if you paint them with child-safe paints! The model also absolutely does not require supports. nine0007

19. Math Spinner

A great way to have fun learning math! Source: 3Dtoday

This math spinner is the perfect companion for learning math. Moreover, it is suitable for all ages, because it is never too late to brush up on your arithmetic knowledge! You can print this finished model or modify it for yourself by removing or adding rings. This advanced design contains all the signs of addition, subtraction, multiplication, division, equality and inequality, as well as a pointer to the string to be solved! On the central insert there are special grooves for fixing. For this version, you will need to print 2 caps and 8 rings of numbers, the rest of the details are printed in a single copy. nine0007

Recommended coverage 25% and layer height 0.2 mm.

20. Jumping turtles

The variety of these turtles is amazing! Source: Thingiverse

Last but not least, jumping turtles! Agree, even the name sounds fun! And a variety of shell designs will give each turtle its own uniqueness. This model uses the same flex concept as the Mini Monster Truck above, making the Turtles bounce when you tap on the body. Also in this turtle, the head can be drawn into the shell. nine0007

The model is assembled with printed H-clamps and does not require glue. All parts are printed without supports. Also note that using the raft (rafts) and brim (margins) options can have a negative effect on the results if you don't then take the time to sand and clean the edges at the base.

If you have problems with head slip, you can try to print 1 of the 3 narrower shaft head files that the author uploaded specifically for this case. nine0007
