Portal Companion Platonic Solids

thingiverse

I was inspired by the Companion Dodecahedron to create an entire set of Companion Platonic solids- the "Portalic Solids", if you will. I managed to find the tetrahedron and icosahedron to go along with my cube, but there was no octahedron available, so I created one! Using John's tetrahedron from GrabCad here https://grabcad.com/library/portal-companion-tetrahedron , I adapted one of the faces to produce an eight-sided version. It could benefit from some refinement, it's mostly hollow and the dark grey circle areas need more depth, and requires a bit more cleaning along the seams, but I think it's a passable attempt for my first creation! UPDATE! I've added the files I had discovered for the other platonic companions, and decided to include them all for convenience. This was a major achievement, I'm being completely sincere right now...
