Hinged Triangle-Square

pinshape

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.blogspot.com, Day 188. Video: Instructions:  Be sure to print with no raft and no support or the model will not work correctly. After printing you need to give the hinges a little "snap" to get them started.  This model is optimized for printing on a Replicator 2 with .3mm/low resolution.  ===== Twitter:  twitter.com/mathgrrl Hacktastic blog:  www.mathgrrl.com/hacktastic Shapeways geekhaus store:  www.shapeways.com/shops/mathgr...  This design and all associated pictures and files are licensed under the Creative Commons Attribution Non-Commercial Share Alike license.
