Summary

Inspired by the boob poop machine! Reverse engineered so it's printable with a desktop 3D printer. Printing in progress on my Makerbot Replicator 2. Design may change based on tolerances.

Instructions

Print the base, both axles vertically (and don't mind the spelling), handle vertically, 2 gears, and lettering. The lettering and gears may be a tight fit to the axle depending on your printer and settings.
Note that I was having trouble getting one of the 4 gears to mesh, so I created an "offset" gear that centers the cavity of the gear vertical to the square hole rather than the tooth. This made my meshing perfect!
