Extruder fan support Ender 3
Description
Hi ! Here is my filament fan support created for my ender 3. It is created in such a way as to be able to mount a fan of the same size as that of the motherboard or the extruder, i.e. a 40 x 40 x 10 mm. I recommend those of the Sunon brand which are very quiet and which operate at 24V compared to the Noctua which operates at 12V. The cooling of the nozzle is based on a ring to have a better efficiency. The fan support is slightly offset towards the front of the printer because depending on the age of the ender 3 the screws of the belt tensioner are not of the same thickness so the support comes forced on it during large printing. The ring was centered around the nozzle of my printer so it may not be exactly the same on your printer. Here are my little remarks on the file and I say good impression to you all ^^
