Bigger 120mm Fan Aperture Door

This is a slight variation of the original 120mm fan aperture door, but has a much wider opening as to not block the airflow of a 120mm fan. I mounted this in an thick walled enclosure so it also has a bit more of a wider base. Fan blades and ring are much thicker and easier to turn. Original kind of slices my fingers. Also Included some plastic washers you can use with M3 round head screws, or you can just use metal washers if you want.
