FrSky Antenna Clamp (for X-series Rx PCB diversity antennas)

Yet another FrSky two-part dual antenna mount. There are several similar designs here, but none of them had quite the mounting orientation I wanted, and I couldn't find one with source code attached, so I coded this from scratch in OpenSCAD.

I get Rx RSSI telemetry on my Tx, and values are significantly higher with this mount on my X-quad. My old mounting arrangement was closer to horizontal plane, with no means to keep the relative orientation of the two PCBs orthogonal. A worthwhile and
