Yes, i noticed that too. They are a bit wobbly. I notice if you look top down, each key has like enough play where the keys aren't 100% straight. I kind of just lived with it but it bugged me a lot.
Lastly too, the enter key and tab key I have to sand down otherwise its like super tight, they wont go up and down. I kind of thought I did something wrong, but Im going to look into the deskeys ones like you said. I was tempted to print my own from resin but if they are commercially available already, id rather buy them.
