For the last week I've been printing whatever polyhedra appeal to me, and today I realized that everything I've printed is a Catalan solid. Today is the fifth, the Triakis Icosahedron - dual of the Truncated Dodecahedron, and the first one so far that has triangular faces. This way leads madness; I'm going to have to print all of them now. Luckily, there are only thirteen Catalan solids. (Of course later I could print all of the Archimedean solids, then the Johnson solids, then Platonic solids and prisms and anti-prisms and arrgggh...)
