Here are O4 Pro mounts for the Quadmula Siren F5 and F5 Mini. I like running the XT60 over VTX and out the top/back of quad, so I made the U shape mount to give some clearance for that. There is a version for T-shaped receiver antenna mount as well like ELRS. V2 is much improved in my opinion, but the antennas aren't staggered in height the way the V1 is.
The U-shaped mount can be difficult to get clean print around the base where antennas meet. I've learned laying it down with antenna facing up, resting along the standoffs (as they will come in file), gives it best quality. I recommend doing 2-3 raft layers to make the bottom of standoff mounts print clean. Support (tree/organic) recommended to improve standoff holes and underside of mount. ELRS mount I wouldn't do without supports.
This is what I've been running for clean prints.
Layer height: .18mm with .30 initial layer
Infill: 70-100%
Support: Organic/Tree style w/ Support/Object XY Distance of 0.15mm
Raft Layers (recommended): 3 layers w/ 0.1mm Raft Contact Z Distance
