This is a quick and dirty remix to fill in the holes for the fan cover because I don't use the fan cover. I like to print dangerously.
There are two versions - One with the fan cover holes filled in with only one layer thick (0.2mm) and another with (0.8mm) fill in.
The thin one, you can punch thru the layer with something sharp if you change your mind. If you hold it up to the light you can see the hole. But if you print in a dark filament, you can't see the holes because its a dark-ish box.
