Start with a cube, carve a rhombic dodecahedron. Carve that into the compound of a cube and an octahedron. Carve the cube into a star tetrahedron and hollow out the octahedron. Make the octahedral frame into 3 interlocking squares, and make the star tetrahedron into a trippy twisty star rattler-then you got what you see here. . .
There you have it, 100 hours later!
