This is a set of what used to be mx cherry keycaps that now have a rubber ducky on top of them. The duck has a little placard thing with a letter of the alphabet.

I assume they are not comfortable to use and there is probably no way to convince anyone that they are, but they're fun.

The keycaps only consist of the alpha characters.

These printed fine for me in pla at 0.16mm layer height without supports. Print in their current orientation.
