About this 3D model

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.
