The idea for this project was to be used as a pump for cooling liquid on a lathe.

Using ideas from other similar designs, i created a new more efficient water pump.
All printed and tested in PLA with a printed rubber seal.

motor i designed this around was 28mm in diameter and the shaft was 2.2mm.

the water is output through a 5mm hose adapter (fish tank bubble tube).

I was able to tap the 4mm holes so i could screw straight into the plastic with M4 bolts

Infill should be 100% other wise water leaks out the sides
