Platonic Solids for OpenScad - v0.7

After losing some hair over the issue, and with some help from Marius Kintel, I was finally enlightened as to why my dodecahedron was not coming out properly.This thing represents some forms of the dodecahedron. In particular, it is combinations of the dual forms (dodecahedron/icosahedron). The .stl files are printed with a radius of 20mm, but you can change that to whatever you want either in the OpenScad, or by scaling.The 'difference' form is probably the most interesting. It makes for a fairly decent calibration piece. It has some nicely sloping overhangs, bridges, and flat spots. I makes for some good tuning between ABS and PLA as well.The challenge with the dodecahedron had to do with OpenScad not being happy with the pentagons I was trying to print. They had to be broken down into triangles, which Marius conveniently did for me. --- Imported from Thingiverse: https://www.thingiverse.com/thing:11224 Original creator: WilliamAAdams
