Ender3 Extruder Fan Cover

thingiverse

I designed an Ender3 Extruder Fan Cover that seamlessly integrates with the original fan housing and retains the use of the standard hex bolts. This custom cover was created to prevent small fragments and strands of filament from entering the extruder fan, ensuring optimal performance. For exceptional print quality, I highly recommend printing this cover as illustrated in the second picture, where the screw holes are positioned at the top.
