Sudoku Puzzle Box

This fully 3d printable box remains locked until the Sudoku puzzle displayed on its top is solved. The puzzle is displayed using knobs pointing to numbers on the box lid. Some knobs are fixed (these are the filled-in numbers on the puzzle) and some are free to rotate. As they rotate, a detent mechanism gives tactile feedback and keeps the pins in place. Once solved, a button on the front of the box is pressed, and the top becomes free to lift off the box. The puzzle is configurable by rearranging different combinations of pins.

Parts:

* box.stl - This is the base of the box.
* pins-moving.stl - These are all of the rotating pins needed to make any Sudoku puzzle. Included are 81 pins, 9 corresponding to each number.

- pins-fixed.stl - This is similar to pins-moving.stl, but contain
