Summary Inspired by http://www.thingiverse.com/thing:7439, I created this burr puzzle piece module. This module is created to be more flexible and support bevel. The source is also on https://github.com/cashlo/OpenSCAN-Objects for update, issues, or pull requests. Included is a Zhuge Liang's Puzzle(第三代孔明锁), there are 4 puzzles you can build with 6, 7, 8, or 9 of the pieces. I have added the solutions as a zip file.
