This is a 40mm bed fan and duct for a Makergear M2 with a v4 head. The usual fan is 50mm, but I wanted dual Noctua fans for silent running. I also switched out the power supply fan for a 60mm Noctua and added Astrosyn dampers on the motors. It is crazy quiet now!

If you have a newer model M2 make sure to use a 24v to 12v converter to power the fan. I used a small R/C model buck converter.
