thingiverse

The puzzles originate from a cube comprising 27 sub-cubes - see object:1570354. The openSCAD code contains a comprehensive list of 7849 three-piece puzzles, any of which can be constructed. Here are six sample puzzles. Five of these puzzles can be assembled into a cube. The puzzle in cube_three_5016.stl can only be solved virtually, as one piece must be broken to form the cube. The puzzle sets are numbered from 1 to 7849 and the STL file names include the number corresponding to each set that makes up the puzzle. Additional details can be found within the openSCAD code.
