NEMA Stepper Motor Cooler for 40MM fan

This is a cooler assembly for standard NEMA 17 stepper motors. It is designed to accommodate a 40mm fan.
It is designed to be printed without any additional support, however you may need a brim.
After printing, snip off the 2 vertical supports for the fan pins. The mount is designed to friction fit fans so no screws are required. This works by compressing the fan between the two pins and the bottom flap.The mount is secured to the motor via a zap strap run through the two holes on the bottom,
