About this 3D model

This Doorknob Puzzle was designed for the MakeAnything puzzle contest. I wanted to make something that became a functional object once it was completed. This should work for a typical door knob. It wasn't designed to be mounted to a door, mainly for simplicity's sake. Parts 6, 7, and 11 are the only parts that need support material. Some parts may need to be re-oriented to print without support materials or to optimize the support material.
