Moonlander placement tray

I just got a Moonlander keyboard, but the halves kept sliding around, which made it hard to try out different positions.  So I designed these trays and used double-sided woodworking tape to mount them on a piece of scrap plywood.

I've used the board on my lap for a couple of days, and that's working pretty well for me so far.  (I did have to make the tabs on the back taller, though, because I kept scooting so close to the desk that it was pushing down the keys in the top row.)

These don't tent—at least, not by themselves—but they're a cheap quick print, and useful for just starting out.
