About this 3D model

Edit: Updated to a v2 which has tighter tolerances and added support for the top nut which prints much better. Use a knife to gently separate nuts from the base. 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, and 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. Submission for the Make Anything puzzle challenge. Supports: None Layer Height: 0.1 Infill: 15%
