About this 3D model

This object prints in one piece without raft or support, fully assembled, hinges and all! The resulting model will hinge from a square to a triangle and back again. The model is based on Dudeney's famous hinged dissection known as the "Haberdasher's Puzzle". For more information, see MakerHome, Day 188. Video: https://www.youtube.com/watch?v=YwwqcHXIfn0
