A regular 1" icosahedron
thingiverse
I'm creating a 1" regular icosahedron, because why not? Thingiverse probably has its fair share, but this one's open-source and free for all to use, each edge precisely defined by the formula 2/(1+sqrt(5)). Designing This Project This design is based on information from https://en.wikipedia.org/wiki/Regular_icosahedron - I took a direct copy of the picture.
