This is a bezel to create a finished mounting for the bind/mode/LED board for a FrSky XHT module. If you are modifying a plug-in module to mount the small board remotely, I believe this bezel will work for those also.

EDIT 2/2/21: I now have a resin printer, which can do a much better job of making this part, so I have added a resin-specific version with label text. The FDM version is intended to be printed face down to eliminate supports, but I'm printing the resin version face up to keep the outer surface clean.
