Fan mount and air flow duct to allow the use of a larger and more powerful Noctua (or other 40 mm) fan to improve the cooling of the cool end of the extruder. This will help when printing PLA in particular to avoid heat creep issues.
The part is printed in PETG without any supports, with the faceplate of the extruder down on the print bed. The holes are compatible with the existing Noctua 40x10mm fan, and the holes used to mount the more powerful fan screws directly into the plastic part. Do not overtighten.
Update: Included the Step file in case you want to make modifications for wiring etc.
