Parametric 27 to 1 Gearset
thingiverse
To improve my Thing-O-Matic printed model, I rewrote the frame in OpenSCAD for a perfect fit. The new design snaps together tightly without screws, turning smoothly. I also added a hand crank for ease of use, resulting in an excellent demonstration object. Check out this awesome creation in action via this video: http://www.youtube.com/watch?v=g73Gw_hJUnE. Remember to print 3 gears.stl, 1 gear4.stl, 2 braces.stl, and one of each other part for complete assembly.
