Centrifugal Pump

thingiverse

The rotor housing (caracol) needs to fit snugly around the standard 608zz bearing. I designed this for a university project, so it's not perfect but it functions adequately. A drill was used to spin the rotor, as visible in the accompanying pictures, where you can see that hot glue has been liberally applied to seal any potential leaks (some parts unfortunately failed during the printing process).
