The "nuts and bolts" appearance of the Hanayama Level 6 Cast Puzzle - Nutcase may lull you into believing this to be a straightforward puzzle, but it is a total brain drain.

To difficult for me, utube explaines how to work. I gave mine away.
Very good build and a fun puzzle. Has a tendency to get jammed when putting pieces back together.
Difficulty rating seemed a bit high. After a quick examination of the puzzle you can understand how to reach the solution. A few minutes of tinkering and the puzzle should be solved.
