Snap-together polyhedron verticies

3D model description

These two triangular pieces can be assembled into any polyhedron based on equilateral triangles. This includes tetrahedra, octahedra, icosahedra, and many others.

The structure of the pieces is such that they resemble both faces and vertices, so the octahedron is also cube-like, and the icosahedron also looks like a dodecahedron. ( a tetrahedron is self-dual, so that doesn't count ).

3D printing settings

Print out two each of Y1 and Y2, assemble into tetrahedron
Print out four each of Y1 and Y2, assemble into octahedron
Print out ten each of Y1 and Y2, assemble into icosahedron

A range of other shapes are possible. I believe the C60 buckyball is possible with these elements.
