A tetrahedron solid created in FreeCAD. A platonic solid is a body where all the faces are identical in shape and size, with identical edges and angles, and the same number of faces meet at each vertex. There are only 5 platonic solids in…
If you've looked for a painter's pyramid before, you're probably aware of the variety of designs out there. I faced the same situation and, while many models had great features, none quite ticked all the boxes for me. That led me to…
The classic Reuleaux Tetrahedron , which is NOT a solid of constant width. You can print the solid in the given orientation with 0 infill and the aid of very few supports (see the print file for my recommended settings). Printed at a 100%…

Part 2 of the geometric series. It will be a great addition to your desk, showing all the cool things 3D printers can do
A very useful tool when treating surfaces, e.g. woodworking. With these tetrahedrons both sides of the board can be treated immediately. Only minimal traces are left at the contact points. They are about 20mm high and as it is a…
Hello everyone, thanks for stopping by! The aim of this project was to create a dual color chainmail and I really like tetrahedron (three sided pyramid) so I decided to go with it. The chainmail consists of lower hexagon link piece and…
A simple tetrahedron which can be used as a paiting cone / painting stand. All four sides are equal, so they can be used in any direction. I would recommend to sand the contact points perfectly flat to avoid any imprints into the wood /…
I recently got quite interested in polyhedrons and geometry for some reason. While I was watching some interesting videos, I also came across Japanese Kumiko (woodworking) technique for assembling wooden lamps. With this inspiration, I…
This Sierpiński Tetrahedron makes a great desk ornament. And it's math-y, if you like that sort of thing. Print Settings In this print I used: PLA 0.2 mm layers Paint-on supports 0% infill (a Sierpiński Tetrahedron has no volume)…
Inspired by Angus once again, I decided to have a look at how I would design a tetrahedron in OpenSCAD. https://youtu.be/5YwvK0dcfmw It turns out the maths are quite simple. I made a simple module to take care of the task, so I decided to…

Its a Tetrahedron (4 sided die ) it gives a fun twist to board games
This started as a "fun" practice model and turned out to be an ok test for inclines and edge supports. It's a pretty torturous print as far as getting the inner edges to look pretty. I plan on using it to play around with support settings…

I wanted to see if I could do a recursive fractal in OpenSCAD. Several misprints later I decided that clever people use polyhedrons. On the the other hand, I just use 'hull'. With enough memory it will render eventually. Print…
Spheroform with Tetrahedral Symmetry Inspired by Angus one Friday night Ultimate Solids of Constant Width . I thought I would combine the ideas of tetrahedral symmetry and a low poly/fast OpenSCAD implementation. Third attempt following…
