I tried the geprc official CNC cage with silicone pads and I find it causes to much ressonance for o4 and gyroflow makes a mess of my video, while this design seems to work better. The cage is printed from petg while the pad is from 85a TPU. To print you need to duplicate and mirror a copy of the cage and the pad for the other side.

Also the camera sticks out a bit so you can use avata2 filters. This isn't the best design for freestyle, if you want to freestyle buy the official geprc cnc cage that will protect your camera this is for cine cursing.

Cage - PETG
Damper/PAD - TPU 85a

Test flight to see how this interacts with gyroflow and does the o4 camera pick up vibration (esc is at 48khz) https://www.youtube.com/watch?v=g8rt8PDFF0Y
