Rhombiminxes date back to 2003, when Laurent Blanc made the first from scratch. This one was independently thought of and designed from scratch. Requires a miniature Eastsheen 2x2x2 keychain cube. I printed this one in 3 colors. Turning is far from perfect, although with some breaking in, it is satisfactory.

If you print this, please post a make. Thanks!
