Tricky 12 piece burr puzzle.

thingiverse

This is a 12-piece burr puzzle that's not the simplest to figure out. The answer requires several pieces to be moved before any piece can be set free. Every single piece is unique. I came up with this puzzle using my own personal puzzle design program, which I wrote in C++ and Qt along with OpenSCAD to create the stl files. My plan is to eventually share the C++ and OpenSCAD program files, but right now the code is unfortunately stuck in a state of constant change and utter disorganization. The downloadable files include three stl files - one for each color of the puzzle shown in the picture. Unfortunately, one of the prints needs support. The generated stl files need to be scaled up significantly. Scaling them by 700% works perfectly well. This will give a puzzle size of 57 mm cubed. I highly recommend printing it in three different colors to make it slightly easier to solve. If you print it with just one color, the puzzle becomes really difficult. Update: I've now come up with a simple solution (no text, just pictures). Have fun. Stefan
