About this 3D model

A 3d-printable displacement pump using a gerotor. It requires many vitamins. Its volumetric efficiency is, well... Somewhat higher than zero. **Why won't thingiverse show my animated gif's!?** Download gerotor-pump.zip to see a moving cutaway view. For it to work pretty much requires acetone-polishing and sanding. Also fish bubbler tubing, 4.5mm BB's, an o-ring, some ABS glue, and oil/grease.
