Radar Scope Desk Console for Round Raspberry Pi Displays (for Waveshare 5in and 4in round)

I run a Raspberry Pi ADSB receiver at home that drives a retro radar screen all day. A round display makes that look far more like the real thing, so I designed a housing that turns it into a proper scope on the desk. It's a round drum that holds the display, a bezel with a 360 degree bearing scale engraved round the glass, and a tilted cradle for the desk. The Pi sits on the back of the display inside the drum. The back plate has a hole for an SMA bulkhead, so you can bring an antenna lead out…
