I made this adapter to fit my O4 Air Unit camera in the Betafpv Micro Canopy Lite (the Meteor series canopy).
It fits with the tiny self tapping screws, but there isn't much room for changing the camera tilt. I then solved this issue by making my own canopy you can find here:

Printed mine in TPU, 0.2mm layers, organic tree supports.
