About this 3D model

WIP. So far there has not been a successful 3D printed engine but this is the idea: A 3D printed spring's energy is captured and released to a series of gears. The design so far is promising but needs work. Update with upload of V1.2: http://joesmakerbot.blogspot.com/2013/01/fully-3d-printed-engine-update-2.html
