rotating regular dodecahedron

A fun-to-play-with 12-sided polyhedron. The inner part corresponds to the insphere of the outer regular dodecahedron (the sphere that is contained within the polyhedron and tangent to each of its faces). It was printed as single object on a 3D printer, and once I cleaned it up it now rotates nicely inside.

Designed with Blender, sliced with KISSlicer, printed on a PolyPrinter 229.

A big thank you goes out to the very nice & helpful folks at the Fort Worth Library for being able to use their printers!
