stepper motors running hot? print this!

designed for Nema stepper motors with 42x42mm using a standard 60mm fan

no support material necessary

  • mount the fan with wooden screws or use double sided tape

  • mount on the stepper motor with double sided tape or a wire strap

(no snap fit due to various position on your printer!)


double side tape for mounting mirrors (the one with 1mm foam in the middle..) works best!

the downloadable stl file is the improved version of the one shown in the screenshots:

  • improved geometry of the side facing the stepper motors

  • added radius to improve airflow

Greater design! What size stepper motor is this made for? Please post the dimensions, too.

Im printing one at the moment, the dust screen is a great hidden feature. I'll post it when it's done. Now I just need a fan :)

...installed 2 of them (x and y axis) - after running hot they're cool now after just 5 minutes of switching on the fans!
