Polyhedra

I played around with regular Polyhedra and made caged ball models where the sides have round centers. Thought they looked nice.

These print pretty well without support material. The caged balls actually have 12 flats (semi-dodecahedron) so that they stick to the platform better and print nicer.

They're all sized so that the vertices lie within a one-inch diameter sphere, and they seem to print a little nicer at 2x scale.

The corners are pointed, and I may later add models that are more rounded off.
