Has anyone made a 3D modeled fidget spinner?
We are making a fidget spinner at school to print on a MakerBot. The center part that spins contains ball bearings. I am not sure how to create a casing to hold the ball bearings.

Michelle,
There are dozens of models in the library. Check them out:

They should give you an idea of how to create the design.
It would be easier, and less expensive to simply knock the bearings out of an existing spinner, but you could also purchase them online.
www.McMaster,com certainly has bearings. But, I bet a quick search online would turn up a dozen suppliers that offer lower quality bearings at a reduced rate.
These spinners are running at a slow speed with no load. Cheap bearings will work fine.
