Sma and rp-sma mounts . Use m2 screws to tighten them on the standoffs.
These are designed around my quadcopter frame designs Aeolus(Aeolus is atm on prototype and not on the store ) and Hermes but can fit any frame that has standoffs at 30.5mm distance.
The square and hexagon patterns are there in order for the sma to "sink" in and stop it from turning. Usually the vtxs with a soldered sma have square bases and pigtails have hexagon.
In offset and centre versions .
I recommend PETG ,ABS or TPU. I print them with no support.
edit: added a 90 degree mount
edit2 : added 30 degree mount
