Dumbbell Cube (in this video called Barbell Cube, but renamed to Dumbbell Cube, as suggested by one viewer) is a challenge for intellectual weight lifters. This puzzle has two Rubik's Cubes that are connected through an intricate gear system. If you turn a face on one cube, a face at the other cube will follow. However, the connections between the two cubes have no symmetry. This makes solving this puzzle extremely difficult. Let's say Rubik's Cube squared.

This puzzle was 3D-printed using nylon-powder SLS technology, which explains its price. It is the very first prototype, costing its designer and maker a lot of money to create. Please do not confuse it for a cheap mass-produced puzzle.
