WARNING: I have made significant imporments to this pump. Found here http://www.thingiverse.com/thing:803035
Simple pump and casing for stepper driver. Designed as a drip pump for adjusting PH in hydroponic system. Good thing because all it can manage is a drip. I'm using a 5v 28BYJ-48, the ULN2003 driver board that it came with and powering it through an arduino. (http://www.amazon.com/gp/product/B0089JV2OM/ref=oh_aui_detailpage_o09_s00?ie=UTF8&psc=1). I designed the pump around 1/16" I.D. x 1/8" O.D. Silicone Tubing (http://www.amazon.com/gp/product/B00G9C9H20/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1). You will also need three 608 bearings,Two 6-8mm m3 bolts & nuts to attach motor, two m3 28mm bolts & nuts, glue to attach the rotorCap and a microcontroller.

BaseV2 - Bolt pattern for driver board mounting fixed and holes for routing wires through bottom of base instead of out the side. Also added a vented version.
RotorcaseV2 - added holes and reliefs to shed any water trapped in case. Slight decrease in inner diameter to prevent back flow.
