Love my Streamdeck, but didn't want it taking up space on my desk when I'm not using it, so I created this “drawer” that mounts to the underside of my desktop with 2 wood screws.

The Streamdeck drops into the “holder,” and then the holder slides into the “mount” which is affixed to the desk. Bend the catch on the back of the holder to get it fully into the mount - this acts as a stop so the Streamdeck will only come out so far - without falling out.
