This is a desk mount for the 15-key Elgato Stream Deck (v1) that secures it to the desktop solidly and has two optional countersunk screw holes in the back.

I hated how flimsy the stand that came with it was and I wanted something that was rock solid. I designed it with the intention of screwing it down into my flight sim platform, but it's really solid with just some double-sided sticky tape.

This inverts the Stream Desk so that the cable routes through the bottom, so you'll have to rotate the Stream Deck device in settings 180 degrees, then manually move the buttons on your profiles.
