About this 3D model

This is a set of regular polyhedra that have runes etched in the faces. Could be considered alien dice. The set consists of one Icosahedron, one Dodecahedron, one Octahedron, two Cubes, and two Tetrahedra, There are a total of 20 unique runes. All 20 are on the Icosohedron. The Octahedron plus the Dodecahedron also have the same 20 runes distributed over their collective 20 sides. The two rune faced cubes plus the two tetrahedrons (all four together have 20 sides) also have the same 20 runes. NEW update: I realized the tetrahedron dice have the wrong form - one rune per face makes it awkward to see what you rolled. I have added two more tetrahedra that have the more conventional three runes around each tip...
