I don't normally make super high level burrs, but I found Frankenstein to be irresistible. This 18 piece burr has VERY unique pieces. Six of them are missing an end grain voxel, allowing for a unique 35 unit arrangement on each face. Incredibly tricky and difficult, simply disassembling this is a feat considering the level 22.214.171.124.126.96.36.199.188.8.131.52 unique solution. Yes, you read that correctly. May the force be with you.
