Summary

This doubles as a rear AIO mounting point for the new wave of ultra light camera mounts that only have 3 mounting points. Fits M2 AIO screws, and should work well with M1.4. Max antenna diameter is likely in range of 1.6mm - 1.8mm depending on overhang droop.

My scale says 0.06g when printed at 0.25 layer height and 0.4 line width, infill doesn't matter since it's only large enough to have perimeters, no infill, no supports.
