This is a new and improved version of my Compound Fracture puzzle. It is slightly smaller, has simplified geometry in the "seam" area, and features a screw-together core. Best of all, it's less expensive than the original.
The Compound Fracture puzzle is based on my Fracture-10 puzzle, but with an additional "twist". With the Compound Fracture, 45 degre turns can be used, allowing face and edge pieces to exchange places. This can make solving the Compound Fracture very difficult, despite the fact that it has only four axes of rotation. In fact, it can be very hard just to restore the puzzle to its' original shape, let alone unscramble the colors!
Compound Fracture comes as a DIY kit of parts, and you will need to supply your own stickers. The templates for the stickers are available in the instructions forum
I recommend that you purchase the puzzle in "Black Strong & Flexible". It costs a bit more than the white material, but it's worth it since the finished puzzle will look and work better. You will need two M3 x 12mm screws to assemble the puzzle.
