I don't know if 3mm balls will make a difference.

They put the calculator into metric mode by default.

No no no!!!! I want the calculator to be a comfortable, antique relic of the last century (like my country) not a modern, efficient useful tool of the 21st century.

McMaster has some with a 1/8" diameter +/- 0.002"

However, I have heard that McMaster don't allow new account from individuals, just companies. I am glad I was able to setup an account years ago that still works.
