Snap-together 3D printable gearset providing a reduction ratio of 27 to 1. Inspired by this thing http://www.thingiverse.com/thing:7379 and I used this script http://www.thingiverse.com/thing:3575 to generate the gears. The primary advantage of this design is that it uses only printable parts-- no fasteners, nuts or bolts.

1. Print 3 of gears.stl, 2 of brace.stl and one each of the other parts. Do not print fullassembly.stl as that is just for the pretty render here on thingiverse.
2. Snap together.
3. There is no step 3
   UPDATE: Don't print this thing. Check out variations by tbuser http://www.thingiverse.com/thing:9454 and makerblock http://www.thingiverse.com/thing:9460 instead.
