DESIGNED FOR A 75MM TALL MOTOR!
This is a NEMA 23 Motor fan housing to help keep the motor cool. It slips over the motor and uses 2 zip-ties to "clamp" the housing to the motor.
It was designed in F360 and in made for a motor that is 75MM TALL, while using a 70MM fan. The fan thickness does not matter, since it is held on with screws. I tried to make a very low profile and clean design.
I needed super heat resistance, so I had mine printed on a HP MJF printer with PA12 nylon. So you will see two STL files. One has M4 threaded holes and one has 3.5MM holes you can thread yourself or use sheet metal screws to hold the fan on.
This can be printed on a FDM printer. Make sure you have supports on, lots of over hangs.
