This Type Of Pump has the Advantage Over Others, of Priming Itself

I Printed This One On My Prusa Mk2 Handmade Clone with 100% Infill (5 Perimeters in Almost Every Part) With PET-G Filament (RIP Bed Mirror)

I Also Used FLEX For The Gasket

I Greased Everything Up, Assembled It And It Works! Quite Well Actually

I Designed The Model Myself In Blender, It Took me 2 Days (4 Hours of Actually)

The Working Principle Of This Pump Is Quite Interesting, It Makes Use of The Gear Mesh Profile To Displace Volume
