FrSky Taranis X9D Plus Antenna (Reversible) Mod Adapter

thingiverse

I looked for a tiny and reversible antenna mod adapter (something with no glue, no sanding, no cut, and if I want to put old antenna back again, just pop off the adapter), but I found only a few large parts... Just print it and put some pressure to assemble as you can see in the pictures. It fits with just a little bit of pressure (not so much), so depending on the accuracy of the printer, you may want to change the X and Y scale (together) between 98~102%. In my case, I printed 100% as it was done.
