Tricky 12 piece burr puzzle.

thingiverse

This is a 12 piece burr puzzle that probably isn't the easiest to solve. The solution requires several pieces to be moved before any piece is freed. All pieces are different. I designed the puzzle using my own puzzle design program written in C++ and Qt together with OpenSCAD to generate the stl files. I plan to eventually publish the C++ and OpenSCAD program files but today the code is unfortunately in a state of constant change and undocumented confusion. The files contains three stl files one for each colour of the puzzle on the picture. One of the prints unfortunately needs support. The generated stl files need to be scaled up. 700% works good. This will give a puzzle size of 57 mm cubed. I recommend printing it in 3 colours to make it a little easier to solve. Use only one colour and you get a really hard puzzle. Update: I have now created a simple solution (no text just pictures). Have fun. Stefan.
