Internal Corner Bracket

An internal Corner Bracket for sheet construction like perspex etc. or could even be used with self-taping screws under a timber shelf, its up to you!

  • The bolt holes are 6mm Dia.
  • The overall size is 40x40x40mm 3mm thick.
  • 15mm Bolt hole edge distance.

I've attached the DXF to help customise.


Adjust infill for application, I used 30% for the enclosure (picture).

Recommend Raft for Rep 2.

Use washers when constructing.

Lamborghini 3D Logo

A 3d logo of the lamborghini brand to be frame for the brand lovers


Start the print with a black filament, when the printer reach the logo layer pause the printer and change the filament to a yellow one then resume the print

have fun

Bolt Keychain (Secret Pillbox)

This Bolt Keychain is easily printable. It's made out of two pieces: a hollow bolt and hollow nut. Both with one closed side. The parts fit together and form a complete nut where you can store little items or notes in.
We don't like wasting material, so we designed it in a way that you won't need any support material.

Echo - 3 Tone Whistle

For the loudest results, print the whistle on its side.
The Echo whistle started as an idea to create the loudest whistle for a 3D Printer and create a more compact survival whistle. This whistle is designed for the person who wants a easy, compact and loud whistle for any situation, ranging from survival to referees.

Testing this print i used 3 different filament types, Wood, PLA, ABS all working perfectly. ABS being the strongest survived any tests i ran it though, throwing it down on the ground, running it over and water. With wood filament it was a bit more brittle but still survived all the tests besides being ran over. The last of them being PLA which survived all tests with a minor amount of damage.

Below in the downloads are 2 different sizes for you to chose from, one with a lower tone and a higher tone.

For the loudest effect, i suggest you cover your ears as i did in the video and blow as hard as you can. Even though the whistle will work with less force than that.

I hope you enjoy this print as much as i did!

Any layer height


15% - 25% you can print higher it may make it feel sturdier but with my experience it doesnt make that much of a difference


You can print this without a raft fine if you have a heated bed. If your printer does not have a heated bed a raft is recommended

Propeller Keychain

Don't forget to tag @umakeprinting when you post your pictures on instagram or twitter! :)

This propeller keychain consists out of two pieces. The case and the propeller itself. You obviously need one of both pieces to make the keychain.

The propeller has one side that sticks out. That side has to be mounted to the bottom of the case. So, towards the side that connects the inside with the outside. A little lube will make the propeller turn a lot smoother.

Ikea Lack Table Brace

The Iconic Ikea Lack Table, Sleek, $8, Versatile. I use them for my 3d Printers and My 3D Printed CNC (in progress) But they have one fatal flaw. When you put a machine that creates oscillations on a table such as a Lack, it follows the oscillations, and weakens over time. This is my attempt to solve the problem and so far it works great.

The holes are designed for standard #5 x 1" wood screws. The outermost holes are aligned to hit the thin piece of MDF that internally makes up the frame of the table. I have had best results using CA glue on the contact surfaces and then securing further with screws. There is not a lot of "meat" internally on the table, so this seems to solve that. The chamfer on the holes is such that button head screws will also work fine.

The screws that meet the leg sections are staggered as to not interfere with on another. I am also well aware the 7 screws plus superglue is overkill, but it works and screws are cheap.

Use 5-6 Walls, and an equal amount of top and bottom layers with 25% infill

I printed these for 3 tables in PETG, Because it is what I primarily use. But I am sure that PLA will work fine.

Uses Approximately 200g of Filament and 4 Braces can fit on a standard print bed.

Please let me know if you personally run into any issues and would like me to change the file accordingly. I have also included the F3D file for your own changing.

Assortment system box 1x1

This Box is one of the sizes of the complete assortment box set from my assortment cabinet video.

Watch the video here to learn more:

The drawers in the cabinet (all 19 of them!) are made in a 6 by 6 grid. So you can fit either 36 of the 1x1 boxes or 3 of the 2x6 boxes. Or any other random variation you may desire!

All the boxes have a place to stick a label, this not only allows you to see what's in the boxes from above but also doubles as a handle to pull them out!

If you want the complete drawings for the assortment cabinet with drawers that fit these boxes, you can download them from my Patreon page:

Gearbox Keychain

This Gearbox Keychain has two working gears. They spin smoothly and have a gear ratio of 1.5:1 (12:8). Other ratios will be uploaded soon! Use a little lube to make it run even smoother!

As always, we don't like wasting material, so we designed it in a way that you won't need any support material.

Gear Bearing

The trouble with 3D printing a ball bearing is that spheres don't adhere to the 45 degree rule, so they tend to print poorly, or if metal balls are used instead, then the bearing requires assembly. This is a new kind of bearing that can only be manufactured by 3D printing and comes preassembled.

It is a planetary gearset and functions like a cross between a needle bearing and a thrust bearing. No cage is required to keep the rollers in place, because their gearing keeps them perfectly spaced. The gears are all herringbone, which is why it cannot be disassembled and also why it can act as a thrust bearing. If you're wondering how well a 3D printed bearing could work under load, please check out my video:

This design is fully parametric and made to be adjusted in the Customizer app to whatever you need. Thanks to aubenc for finding a problem in the first version.


The key to any bearing is the tolerance between the moving parts. Since this is printed all at once, you want the minimum tolerance possible, where any less would fuse the parts together. I print these with the MakerWare medium defaults on my Replicator 1 and it requires a fair bit of torque to break it free at first. It's designed to fit onto the standard English hex size for screwdriver bits, so you can use a tool to help turn it. Running it in a drill for a few minutes helps to smooth out the rotation.

You can adjust the tolerance in Customizer if you need. You can also change the dimensions, numbers of planets, numbers of teeth, etc. Normal gears use a small pressure angle in order to transmit torque, but here I use a large pressure angle so that they transmit force better (hence why they look more pointed than usual). Your chosen number of sun gear teeth is approximate because planetary gearboxes turn out to be quite constrained in terms of what tooth numbers will fit. See the beginning of my code for the equation I came up with.
