Microsoft Surface Pro LED cover and cable strain relief

Simple LED Cover and cable strain relief for Microsoft Surface Pro (2017)

My wife objects to LEDs in the bedroom, so I designed a simple cover for it. While I was at it, I decided to add strain relief to it as well since the cable comes off vertically. I have no idea if this is necessary, but it was easy to add, so why not?
