Logitech MX keys under desk holder. I found this really useful when I want to get some extra desk space when not using the computer. Also it protects your keyboard from dust when not in use.
This is a remix from a model from Thingiverse. I found the original one too sharp on the edges and it could easily scratch the keyboard or your hand.
Print in 0.2 or 0.3 layer height (PLA or PETG). No Support needed.
Insert your keyboard in holders and measure the distance from the holes. Give it a few millimetres more (don't make it too snug).
