Hanayama Cast Puzzle - Nutcase - Level 6 in Bloomington, MN

The nuts and bolts appearance may lull you into believing this to be a straightforward puzzle, but it is a total brain drain. Inventor Oskar van Deventer presents two challenges: 1) remove the small nuts by disassembling the nutcase, and 2) change the order of the wording on the bolts from nut-case to case-nut.
