V1 - Designing the Wolds Best 3D Printable Penis Pump I saw this idea on the film aston powers. swedish penis pump. I am bored to death today in the office so I decided to quickly model up a printable penis pump.. I left room around the pump plunger for a rubber seal. so the pressure is tighter.I think this might be the first printable penis pump on youmagine ?WARNING !! this design has not been tested ! Enjoy ! Ian :-)
