3D printed bearing balls?

[anrveira]

Hi, great job, thanks!

I can't find what diameter is needed for the balls used in the 3D printed bearing. Where did you get them?

Thanks.

Thank you!
I used 6mm BB pellets. You should be able to get them from many online sites or possibly in your local stores. I'd avoid super cheap, poor quality ones because they often have defects that make them not round...
