Bản sửa O-ring cho Xiaomi Mi Pump 1S

My Xiaomi Mi Pump 1S stopped compressing air last week, but the motor was runnig ok.

A quick disassembly revealed a damaged cylinder o-ring. So i designed and printed a new one. 

It's running fine, inflated two bycicle tyres, and corrected the pressure on 4 car tires. Not shure how long  it will hold up.

The used material was Recreus Filaflex 60A TPU. 4 minutes print time.

Posted the .3MF file containing the print settings. Make shure the filament is dry and  the extruder gears have low tension, if you use this filament.
