Nonplanar Tetrarhons

Tetrarhons are four rhombic dodecahedrons joined at their faces. Among the 28 pieces there are 14 nonplanar ones, which can't be turned to get all four parts touching the ground. You can get different constructions with these pieces, if you place corners with three edges at the bottom (e.g. a tetrahedron) or corners with four edges at the bottom (e.g. a L-shaped roof) or rhombs at the bottom (e.g kind of boxes).
