This is a slim and significant lighter stepper cooler for a 40mm Noctua fan. It is lighter because it works without screws.
In my tests the stepper is not geting warmer than 45°C. The shaft with the drivegear stay at nearly the same temperature. Even at a 6h print at 250/75 in a full enclosure. This prevents clogs by softening your filament to early.
Print instructions
Print it in PETG.
You need a 40x40x10mm fan (i use a noctua) and you have to solder it to your extruder fan.
Print it upside down.
