The puzzle is a fully functional extended cubeoctahedron. It has all the same peices as a cross cube, though solving it will be different because the inner corners are exposed to the outside in this puzzle. It turns quite nicely.
If you order from shapeways you will have to buy screws (six 4-40 machine screws) springs (if you want them) and stickers yourself. If you would like a fully assembled and stickered puzzle, contact me (email@example.com) to purchase one from me.
