5V 140RPM Full metal gear motor GA12-N20 waterproof motor 3V-9V


The plastic head on the motor shaft can be easily taken out.
The output shaft and back of the motor are waterproof and protected, so I believe that most of the disassembled motors are in good condition.

Output shaft diameter: 3 MM (2.45MM with flat position)
weight is 14g
