This is a remix version of this: https://www.thingiverse.com/thing:4580010 Credit goes to cdsmakestuff. A Noctua fan mod for Ender 3 Pro hotend cooling. Both fan ducts use M3x20 to be secured if removing the underneath dampener. The Fan duct for the tip requires minimal support outside the shroud, no support need inside the duct. The heatsink fan requires a zip tie to secure the shroud to the heatsink, ideally over 10 cm Easy to print and lightweight. about 2h24' for 50mm/s and 2h09' for 60mm/s P/S: I'm not the definitive guy to trust on doing fan mod. Please do research before modding. TLDR, use a buck converter to safely supply 12v to both fans.
