608 Ball Bearing (good tolerance)

thingiverse

I've tested numerous 1-piece or multi-part ball bearings, but none of them performed as expected. They consistently emerged in a single solid block, requiring hours to install or suffering from excessive friction. In response, I designed this alternative solution. It's been incredibly effective in my light spinners, which typically struggle with metal and heavy bearings. This design works seamlessly without the need for subsequent oiling after the initial use. To achieve optimal results, I recommend printing it using minimal light supports that only make contact with the build plate. Once printed, simply remove these supports with a precision cutter. https://youtu.be/72AY1O8pVXE
