Print in Place Puzzle

This is my version of the Hanayama nut-case puzzle which allows you to print the puzzle in one piece, no assembly required. Download, slice, print and enjoy trying to figure out how the case opens without getting the secret spoiled! There's space inside to store a small object or note once opened. The puzzle can get frustrating, but be gentle with the threads! It should be easy to open once the puzzle is solved. Supports included in model.
