After searching in vain for a suitable option, I ended up making my own.
It is a parametric design, so you easily adjust pretty much any dimension in Fusion's parameters table to fit your remotes.

I didn't put keyholes for screws bc remotes aren't heavy and Command(TM) strips so it doesn't leave any permanent damage to the furniture you mount it on.

This one is dimensioned to hold remote controls for:

• slot 1: Video projector
• slot 2: Amplifier
• slot 3: Fire Stick

Design has a few features to prevent the need of support, minimize material and make grabbing/placing back the remotes easier.

Fusion 360 file is included.

0.2mm layer height

Gyroid 10%

Sovol SV06 Plus (Not SV07, the SV06 Plus is not available in the Thingiverse options)
No need for bed adhesion features.

It's the first time I'm using parametric design. This feature is great for tweaking the design and sharing.
