pet blower

Requires a 130mm diameter vacuum cleaner motor (the one for 29 yuan on Taobao), a KCD4 rocker switch, and a wire. Also 7 sets of M4*10 screws and nuts are needed to secure the handle and bracket. Make sure to use high-temperature resistant filament like ABS, otherwise the casing will soften and deform after a few minutes of continuous operation. The motor must be glued firmly, otherwise the counter-torque generated at startup will cause the motor to spin on its own. You can also add a soft starter for power tools to make the start less abrupt. The front and rear covers are fixed with threads, so when screwing on the front cover, turn the front cover and the wire simultaneously to prevent the wire from desoldering or breaking.
