Pump Impeller

The impeller for the garden pump was created as a spare part. I have to wait too long for a replacement from China. It is not a sin to do it yourself when the printer stands on the desk.

Yellow one is the original - lemon is My spare part.
Rotor dimensions:
Propeller diameter 31mm
Blade thickness 2mm
60 degree angle between blades
Z high 20mm
Axle diameter 7mm
