I made a custom acrylic case for my cherry brown keyboard. It's held up by 3d-printed pegs, the plastic rises a little in the bottom center area, and it's kinda creaky in parts. Plus, it's charred up or melty-looking around the edges. But hey, It's 100% custom made, if you're into that sort of thing. Just asking enough to fund the purchase of another fullsize board.
Attached is a pic of the keyboard in progress, there are two more screws and standoffs now. New, non-ricey keycaps in a month if you are willing to wait.
