I based this on the aluminium grommet that comes with SpeedyBee frames. You only get one in the frame kit, and the DJI O4 Air Pro comes with two separate VTX antennas, so you need an extra one to fit rear antenna mounts that have two SMA holes.
The SMA holes are 6mm in diameter. This grommet is 7mm, so you have to squeeze it in there - it is deliberately a tight fit so it won't fall out.
Print in TPU - you need some flex in the material or it won't be a tight fit.
I have test flown on this and it worked fine, I had one minor bump (upside down landing) and the antenna did not come loose from the grommet, but it certainly is not as secure as the SpeedyBee aluminium one, because that has grub screws to clamp down on the antenna stalk.
