Ender 3 Pro PSU Cover for 80x80x25mm Fan
thingiverse
I removed the fan grille and widened the fan hole to 80mm to minimize the sound through air distortion. The holes for the fan screws are widened, you should now screw them in without damaging the material around it. I added the part for the deeper two screws again so you can use all four screws to hold it in place.
