Medial Rhombic Triacontahedron:
When I scaled down the outer vertices, it looked to be created from (or based on) an icosahedron. So, I started there. The one below on the right is mine. The others are from assorted other sources.
My question is, is mine any less a Medial Rhombic Triacontahedron? It’s much more compact and easier to reduce (presentably) to the edges minus the faces. It subdivides well. The others don’t. The edges extend into and beyond. They just look uglier by comparison. As a solid, I suppose. But, in trying to save space, something that is limited to the eseential edges and subdivides accordingly, just seems better constructed (at least for purposes of 3D printing, where cost matters).
