Reuleauxminx Puzzle (Tetrahedral Megaminx)

grabcad

Couldn't figure out whether I wanted to make a dodecahedral or tetrahedral puzzle, so this seemed like the obvious choice! It's a simple Face-Turning Dodecahedron (colloquially, a "megaminx") transformed into the shape of a tetrahedron. The "pillowing" effect is necessary, had I used a regular tetrahedron, pieces would either fall out or collide mid-turn.
