Bill of Materials
Description
All components of this design are designed for 3D printing, so no external purchases are required (assembly only requires 10 M3*16 hex screws and nuts) The principle of this pump is that when two gears mesh and separate at high speed, a pressure difference is generated between the teeth, and this pressure difference can be used to create a powerful self-priming force
