I printed @m013's mount twice but could not get my lolipop 2 to fit into it. I suspect this file is meant to be printed using TPU or some other more flexible filament but all I've got is PLA. I made the sides a little shorter to reduce any blocking of the signal (if any) and made the slits for the zip ties a really close match for what came with the quad. The Fusion 360 file is included if anyone needs to adjust the print further.
I only put supports under the bottom of the cup and printed on the flat bottom of the plate.
