Parametric 27 to 1 Gearset
thingiverse
The original had tolerences that were too loose when printed on my Thing-O-Matic, so I started re-writing the frame in OpenSCAD. This fits together perfectly on my printer and works great. It all snaps together nice and tight and turns smoothly - all plastic no screws! I also added a hand crank to make it easier to turn. This makes an awesome demo object! Here's a video of it in action: http://www.youtube.com/watch?v=g73Gw_hJUnE Instructions Print 3 x gears.stl, 1 x gear4.stl, 2 x braces.stl and one of each of the other parts
