Stripsphere20

The 20 rings on this sphere (10 sets of 2 parallel rings) are parallel to the 10 great circles through the 20 vertices of an dodecahedron , and are spaced to give the best looking pattern. This was plotted in Mathematica, thickened in Blender, cleaned in Netfabb Cloud. Strips are thick enough to print in colored polished plastic. Contact me if you wish a print in metal, as it will have to be thickened a bit more. Smaller, it would be a nice pendant in brass or silver; I'll do that if wished.
