Received over recent weeks. Stella 4D program helped with the geometry. I hope to progress to some more complex models
3 recent additions to my collection of regular polyhedra which now totals 10. The geometry of some harder than others, in general find it easy to work them out from scratch, imported models often suffer from inverted normals etc. I create stl files via Rhinoceros; provided the polygon count is kept low they upload easily enough.
