Pseudorhombicuboctahedron

On this page

The Pseudorhombicuboctahedron puzzle showcases the geometry of the elongaged square gyrobicupola, a rhombicuboctahedron that’s been ‘gyroed’ by 45 degrees. There are eight shallow turning axes on the triangular faces. If these cuts were implemented on an ordinary rhombicuboctahedron, the resulting puzzle would be fairly simple like a Compy Cube. But due to the skew of the top and bottom axes, a complex cut pattern emerges, with 218 visible pieces.

The puzzle is implemented with a 3-layer shells mechanism printed out of ABS and white SLA resin. An optional jumbling move is possible between the gyroed axes, which mixes up some orbits that would otherwise remain separated.
