Source Two Electronics Top Mount
thingiverse
Probably fairly unique to my setup, but here's a combined mount that might be of use to anyone else. It attaches using the existing screws that hold the top plate in place, without replacing that plate at all. The mount has space for an FrSky RXSR receiver, a Chaos VTX, a 12mm buzzer, and a Matek GPS/Compass module. Printed in TPU for flexibility with the antenna, and to hold the buzzer securely.
