MKS v1.1 controller cover for Sunhokey Prusa i3

May fit any machine with a MKS v1.1 board but came in handy on my Sunhokey Prusa i3. I've hit the back of my hand a few times on various pins on the control board doing filament changes so figured a cover of some sort was needed.

Added two 30mm fans just in case. The stepper controllers run about 50C without the case so this should help keep them cool now that they're no longer in open air.

For spacing I used 5mm nylon standoffs under the control board and 20mm standoffs on top.
