My steppers are getting too hot (~50°C), so I think is a good idea to install 40x40x10 fans in all of them. With that you get at least 5°C less.


First check if your NEMA17 stepper has recessions on corners in order the snapfits to be able to clip it.
The 40x40x10 fan I bought got 2.8mm holes, so I design the part for M2.5. Maybe you need to open the holes for M3.
You´ll need two M2.5x12 screws and two M2.5 nuts to mount.
I left enough clearance in the snapfit so you´ll need a few finishing in your printed part.
It´s very light (3,2g) and prints in 26 min.
