These are easier to load your antennas through than others I've tried. I've got it so it sits lower than the top of the standoffs for a tight build. 3mm antenna tubes bottom out so in a crash they're not going to smash down into the antennas, pinning and possible damaging them.
UPDATE on sugested filament:
I still think the mount is perfect but I no longer print it in ABS. One print in TPU with suport on will out last the frame. Ninjaflex and Simiflex is always the best TPU!
