Balls spinner (simple and economic) by facucor

Last crawled date: 4 years, 3 months ago

I designed this spinner because i only had 1 balls bearing(608-RS) and a lot of little balls(15.4mm diameter, you can change it)!
It is cheaper than a normal spinner which uses 4 balls bearings.
Now I'm trying to improve it using steel balls. Please let me know if you can do it!
Hope to be useful!
