The design files for this thing have been removed as a protest against Stratasys after their decision to file a patent infringement lawsuit against Microboards Technology. Their decision is extremely destructive and also underlines that the patent system is obsolete as it no longer serves any purpose for the betterment of society. Its main role is as a blunt weapon used by incumbents to hamper innovation. I see absolutely no reason to continue indirectly supporting Stratasys by providing free content to Thingiverse. Water jet vacuum pump (Aspirator / Bunsen pump / Venturi pump). In its current state, it will happily implode an empty soda bottle, but the theoretical limit for such a pump is the vapour pressure of water. 1) Slice & print pump.stl using 100% infill for maximum strength 2) Sand and glue the pieces together using acetone. Paint the seams with acetone/ABS.The design is for a vacuum hose with an outer diameter of 9 m.m. and a water hose with an inner diameter of 13 m.m. The design can easily be modified to accomodate other dimensions.Insert the vacuum hose (a semi-rigid thick walled PVC tube will do), and connect a standard garden hose using a small hose clamp.
