Description
update : a revised script and set which includes 4,5 and 6-fold vertices ( slash facets, not sure which to call these ) can be found at thingiverse.com/thing:4934 and thingiverse.com/thing:5028.
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 ).

Instructions
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.

There is a self intersection where the male connector meets the body. OpenSCAD will not import this file. Can you please either fix this problem of upload the .scad source so I can.

I made a nice structure using these parts, I only used Y1.stl and Y2.stl.
Printed on a UP! printer, (pp3dp.com).

This looks very simple and fun. What did you use to do the modeling?

Maybe I printed too many walls (2) or too much infill (30%), but I can snap them together only under hot water (PLA). They make a very nice connection though. Inseparable (when cold) and frictionless.
No, that's correct. These were designed for the elasticity of ABS and don't really work correctly with PLA.
