This is a keyboard tray mount I made for the DIWANGUS HOTAS desk mounts. Those mounts are a good deal, on Amazon, but didn't leave room on the top of the desk for my keyboard.
This mount is in two pieces, just glue or velcro them together after printing. The base grips the top of the DIWANGUS mount and has feet to support the keyboard tray. The base is angled 15 degrees for comfort. Using a cheap HP keyboard, but it should fit most, if not, scale up the Z axis a bit to fit your keyboard.
The tray is 280mm and fits my Anycubic Kobra Plus, Scale it on its X axis to fit your printer. The narrower, the less stable it will be, YMMV. Without velcro, 280mm wide works great. Narrower and you may need to stick or velcro it down for stability.
