Ender 3 (Pro) Power Supply Fan Silencer / Cover

prusaprinters

Remixed from timqui's cover to replace the large rounded edges with chamfers for a much cleaner print and a version without the central hole. This style does not make the fan silent, but does seem to reduce some frequencies enough to make it more tolerable.Supports should only be required for the mounting tabs. Ensure your slicer overhang threshold is set to avoid generating supports around the perimeter (support overhang angle to 50 in Cura I believe).Be sure to only have one screw removed at a time. The fan will fall down into the power supply if both screws are removed.Mirrored alternative versions are included for some Ender 3 Pro models with a rotated hole pattern.
