I've found this nice simple holder for my Samsung TV by Smurfbyter : Samsung remote under desk mount by Smurfbyter | Download free STL model | Printables.com.
It was a perfect fit, but I wanted to add a magnetic adapter for charging the remote. I use those cheap one from amazon : https://amzn.to/3TExJS9.
Bonus point : the remote snaps into place :)
The author remixed this model.
Added a hole in the rear of the panel to place a magnetic charging dongle.
