Nonplanar Tetrarhons

thingiverse

Tetrarhons consist of four interconnected rhombic dodecahedrons. The 28 total pieces contain 14 non-planar ones, which cannot be manipulated to have all four components in contact with the ground. Various constructions can be achieved by placing corners with three edges at the bottom, such as a tetrahedron shape, or corners with four edges at the bottom, like an L-shaped roof structure, or rhombs at the bottom, resulting in box-like formations.
