This is made for a Roccat Vulcan 2 but it may work on other keyboard. It's not a perfect fit on the keyboard side because I've added double tape to make it not go away when I click on it.
To place the Stream deck, place the bottom first then push to fix the top. It's very tight so it won't move.
That's my first make so I hope it's fine and will fit the needs of someone else !
