Remix of JGMaker Magic's fan silencer. I removed the center hole, rounded some edges and added an additional baffle. JGMaker's design seems quieter than others I have tried so far.
Print "Ender 3 Pro PSU Silencer v2.stl" for the Ender 3 Pro. v1 is closer to JGMaker Magic's. Mirrored versions are include for rotated hole patterns.
Supports are only required for the mounting tabs. I adjust my support overhang angle to avoid generating support for the chamfer around the outer perimeter. This produces a cleaner part that prints faster (for me at least).
Only remove and replace one fan screw at at time to avoid dropping the fan into the power supply.
