Hinged Triangle-Square

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".

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. If you have problems printing on a different machine then tell me details in the comments and I will post some tighter/looser variants that might work better. **UPDATE: New post about this model, new versions for 3D printing on different printers, and new mathematical advances, at Hacktastic: [Hinged Triangle-Square](http://mathgrrl.com/hacktastic/2018/11/hinged-triangle-square/)** Don't have a 3D printer, or want something fancy?
