27 to 1 reduction gearset
thingiverse
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. Instructions 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. Snap together. There is no step 3UPDATE: Don't print this thing.
