NONE OF THESE PARTS HAVE BEEN TESTED IRL... PLEASE LMK IF THERE ARE ANY PROBLEMS.
Also, to whoever made the hero me 60mm fan adapter, I'm sorry, but I forgot to check who made it.
This is a modification of the Hero Me Fan Duct. Thanks to Mediaman3D for the ducts that were tested with computational fluid dynamics and base. To select the base, go to the Folder and select based on the Direct Drive Extruder (or bowden if you don't want direct drive). Then, print the rest of the files, and print the BLTouch Mount only if you have a BLTouch. The BLTouch Mount has not been tested IRL, but the offsets should be about -33 X and -7 Y (this is the first time I'm doing this so this may be completely wrong please double check). I recommend printing everything with tree supports touching buildplate only in PETG.
The single 5020 blower fan should be able to push enough air for part cooling at only 50 percent speed, meaning that it should be pretty quiet. The 60mm fan has very good CFM due to the fan being larger than the standard 40mm fan, so it should be extremely beneficial for keeping the hotend cool.
