I have never tried it but I am real curious for low speed things like that, I think it would come down to your printer being able to print something small enough. There are a bunch of print in place bearing designs on printables that I have run across too.

I usually use 608 bearings for that kind of thing because they are really cheap on Amazon as well since those are used in roller skates and skateboards and stuff. I am definitely curious though so you should reply if you try it out :D
