Water Pump

Simple water pump. Had old electric motor with pinion from printer. I tried to get rid of the pinion but it was difficult to remove and i was afraid to brake the motor. Everything fitted nicely without glue. The impeller needed some nail file to get rid of the 1st layer edge that is usually wider than the rest of the part. There is also holes for the screws but works fine without them.

Morot diameter ~27,6mm, the hub in before the shaft is 10mm and the shaft is 2,3mm

Added another pump hub for 2,2mm shaft. Just heat up the shaft and then press the part to the shaft.
