I recently purchased a Radiolink RC8X, as i heard I could use it with crsf compatible modules, such as the Radiomaster Ranger (which I picked because it has a screen, as the firmware provides no support for elrs).
After figuring out how to make it work, the piece that was missing was a proper way of mounting it to the Radio. Still, the only thing that I could find that anyone had designed to mount to the radio was a GoPro mount for the radio - so I decided to do the lazy thing and just model the camera side of the mount on a baseplate for the module.
In case you found this because you are looking for a way to mount the module to the radio, the radio-gopro-mount I found is at https://cults3d.com/en/3d-model/various/radiolink-rc8x-phone-camera-holder . Sadly its under cults3d's private license, thus I can't include or remix, but you can get it from there.
The author marked this model as their own original creation.
