Ender 3 Hotend Dual Fan Cooler
thingiverse
This mount allows for attaching two Noctua fans to cool the Ender 3 Pro hotend using only the two mounting screws for the original metal cover. This fan mount fits over the top of the original metal cover so that the original blower style fan is still attached for cooling the tip. I printed the mount all as one piece, using a *Tree Support* when sliced in Cura. I had to take all of the rubber anti-vibration pads off of the Noctua Fans so that they would fit inside the two fan covers. Once they are in there, the Fans + Covers should slide into the mount like a cassette and form a tight fit.
