After breaking a SMA to N-Type adaptor for my Meshtastic antenna, I designed a protector that helps stabilize the connector with an added bonus of making it easier to attach and remove the antenna without any wrenches. 

There are two versions; one that's 10mm tall if you don't have any space restrictions and a second for TonyG's RAK19007-mini/RAK5005-mini case for Meshtastic that's a little shorter to clear the lanyard attachment point. 

While this was printed with a 0.4 mm nozzle at 0.2 mm layer height with three perimeters and 25% gyroid infill, It should be compatible with whatever settings you want to use.
