Snake Cube
thingiverse
Upon discovering Snake Cube Puzzle on Thingiverse (http://www.thingiverse.com/thing:10486), I decided that this would be a great opportunity to learn FreeCAD. To assemble the puzzle, first print CompleteColorA.stl and CompleteColorB.stl in different colors at 20% infill with 0.1mm layer height. This will result in 27 cubes: 9 straight-holed, 16 with 90° corner holes, and 2 larger-holed on one side. Thread these cubes onto an elastic string as shown in the third picture. The two larger-holed cubes should be end cubes with bigger holes facing outwards. Tie knots at each end of the thread inside the big holes (ensure they don't slide through smaller holes), and tighten the cubes as much as possible. If you encounter difficulties, watch this video for guidance: http://goo.gl/5efPB0.
