I just removed the hand cranck, gears, bearing and replaced the parts with a brushless motor I had from a T-rex 450. There should probably be some sort of feet for mounting it on a surface, but that is up to you!
It is quite loud! So mind your neighbour :)
New impeller unit with screw for fixating the wheel on the axis of the motor.
Printed it without support, PLA.
The wheel is designed to fit a 3mm shaft.
Mount the motor in the housing and push the wheel on the motor.
