About this 3D model

These are simple regular solids that are, well, solid. They may actually use less material than the hollow dodecahedron at http://www.thingiverse.com/thing:198 if you let skeinforge do its thing. (I didn't actually check.) These are two of the basic shapes in pyTopMod, except that it builds them edge down. If there's a way to align faces in TopMod, I didn't find it. I used blender to rotate them to be face down. I also tried TopMod's soccer ball, but it has too much overhang and failed to build. The whistle is in the picture because I built the plain whistle http://www.thingiverse.com/thing:1222 and built a 1cm icosahedron first and dropped it in during build.
