Ender 3 Control Fan Cover

Ender 3 Control Fan Cover

thingiverse

This is one of the first things I print for a new Ender 3 printer. It is a cover to go over the cooling fan for the control circuit board. Unfortunately Creality put the fan opening directly under the print bed, so any debris that falls off the bed ends up in the fan. This cover protects the fan and sends the air flow forward and rearward without reducing its efficiency. I reuse the mounting screws to attach the cover over the fan.
