Voronoi Tetrahedron Matrix (Star Tetrahedron)

This object contains 8 tetrahedrons assembled in an isotropic vector matrix. Edges of each tetrahedron are 50mm. Minimum diameter of voronoi structures is 3mm. The object has a small footprint relative to it's size, so printing with a brim is a good idea.

The above image shows a print at full scale, but I recommend scaling to 50% and printing with a 0.4 mm nozzle at 0.1 mm layer height.

See here for an example of at 64 tetrahedron printed at 50%: https://www.thingiverse.com/thing:4350911

This would make a great Christmas ornament for the math geeks in your life!
