This is a small model to relocate the SMA connector (without modifying the case) for the most recent model of the OrangeRX DSMX JR module (with the screws on the back/bottom) from coming straight out, up 90 degrees.
Make sure you print the main adapter with the slot/hole facing down, as displayed in the preview above. There are internal overhangs that do not play nice with a simpler orientation
This lets the antenna avoid interfering with the bracebar on most transmitters.
I use mine with a Turnigy 9X.
