The original Pennyhedron has rhombic-dodecahedron shape. That puzzle can be pulled apart by putting three fingers from each hand at the right places on the faces. The challenge is where to put ones fingers, as all faces look the same. Surprisingly, many people have difficulty solving Pennyhedron, even when the two pieces have different colors. So Pennyhedron Senior may be a good puzzle for those who have already solved the original Pennyhedron.

Pennyhedron Senior is constructed from 30 rhombic panels, 15 for each part. A 3D-printable mould is included to align the parts for gluing. Make sure that no glue seeps out. The .zip file also includes STLs for the original Pennyhedron puzzle, and for the cubic Pennyhedron Junior.
