Interlocking Puzzle Cube #1

thingiverse

This is my first version of a challenging interlocking puzzle. I created this project in response to a challenge between richgain and Bram Cohen (see the full story here for details): "[find] printable interlocking puzzle cube designs with a level higher than 1, i.e. needing more than a single move to take the first piece out." I have now developed several computer-generated solutions, and this is the first one I'm sharing. According to BurrTools, you need 5 moves to remove the first piece (the xmpuzzle file is provided). This puzzle is easy to print (no support or joints are required), but it's not so easy to solve. Feedback, pictures, and tips are welcome.
