I have a 4x USB switch from AIMOS that has a tiny (3cm diameter) remote. The vendor delivers it with a double-sided sticky tape to mount it somewhere. Did not last long so I decided to make a decent fixture for under the desk.
I printed it in black PETG, but PLA should also be fine. I used supports on the tray.
The smaller part is pushed into the holder to lock the remote and hold it in place firmly.
The author marked this model as their own original creation.
