Cubes are boring. Octahedrons and tetrahedrons are a much more interesting way to tile 3D space.

The octahedrons are printed in two parts. Glue the flat sides together.

Octohedrons and tetrahedrons tile 3D at a ratio of one octohedron for every two tetrahedrons.

These files are designed with zero tolerance between the nubs and holes to ensure a tight fit. Print with a 0.4 mm nozzle at 0.1 mm layer height for best results, and expect to do a bit of post-print filing and trimming for the perfect fit.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
