Controller Fan Cover

Controller box fan covers for the Ender 3 are pretty much expected, so here is my contribution.

My design emphasizes simplicity, maximizes airflow, and minimizes filament.

I decided to use the lid mounting screws rather than providing something which clipped into the fan hole (which, potentially, would slightly impede airflow).
