Review on 🎮 Convenient Bed Mount Holder: Gamepad Under Desk Stand for Xbox One, Switch, PS4, PS5, PC, and More - Brainwavz UGC-Z by David Skyline

This is a 3D printed item, not a molded piece of plastic. So if you have a 3D printer or have access to one, you can probably find the file somewhere for free. It's fairly durable and comes with a strong 3M cling foam tip that attaches to the underside of your desk. I use it on my standing desk and the Xbox One controller is relatively secure, although there is a slight hesitation and I occasionally knocked the controller out of the holder. I suppose it works well enough for most common controller styles, but I haven't tried it with a PS4 or Steam controller, and it definitely works well for under-desk mounting your headphones (probably works better for headphones).
