I designed this stress-relieving spinning top to test myParameterized bearings。

This bearing needs to beNine 6-millimeter air gun pelletsonly then can it work normally.

Although it's completely 3D-printed, it rotates smoothly and performs reliably, butPlease rememberAnd its performanceIt won't be as good as a real stress-relieving spinning top.

This model canWith or without a bearing cageUse it. However, to improve stability and ensure smoother rotation, I strongly recommendWith a retainerUse it.

I provided information aboutBearing assemblythe document, because it requires an assembly process.
