About this 3D model
This is a derivative of Skimbal's CD-Rom motor pump, [thingiverse.com/thing:4881](http://www.thingiverse.com/thing:4881), but with screw mounting and a 6mm circular outlet. Youtube video of it here: http://youtu.be/us2KlyBPEaU I may design a V2 sometime, possibly without screws and without need for any support material.
