Portal Companion Platonic Solids

I was inspired by the Companion Dodecahedron to have a full set of Companion Platonic solids- the "Portalic Solids", if you will. I was able to find the tetrahedron and Icosahedron to go along with my cube, but there was no Octahedron to be found- so I made one! Using "John"'s tetrahedron from GrabCad here(https://grabcad.com/library/portal-companion-tetrahedron) I stole one of the faces to create an 8-sided version. It could use some work, it's mostly hollow and the dark grey circle areas could be thicker, and needs a bit more cleanup along the seams, but I think it's a passable attempt for my first Thing!

UPDATE! I've added the files I had found for the other platonic companions, and decided to include them all for convinience. This was a triumph, I'm being so sincere right now...
