Hanayama Huzzle L3 O'Gear

O'GEAR consists of solid metal cube with various slots on all six sides and a five-pronged, gear-shaped piece. The object is to remove the gear from the metal cube. The puzzles works somewhat similar to a 3-D maze in that there are numerous dead ends. Taking it apart is only half the fun - can you assemble it again afterwards?
