Simple clip-on keyboard feet for the Keychron K1. It raises the back 13mm off the table surface. It's thin enough to fit between the two switches above the F1 keys. There's also a tab on the back to allow easier removal, since you can't slide it off due to the existing small rubber feet.
I used PLA but I would think PETG would be fine too. It will slide around on a hard surface, so you may still need some kind of rubber surface underneath for non-slip. I tried printing in TPU as well and this does work and help with slip, but doesn't hold as well to the keyboard.
Enjoy!
