Fidget roller

I liked the design of ONI Roller by 5quig, but the fit was too tight. This design is a bit shorter (to be more like AA batteries you can roll in your hand), and I placed small bumps on the contact surfaces between the plastic and bearings to provide a tight fit that's still pretty easy take apart and put back together.

I've created a few of these to give to people, but I don't have one on hand right now to post photos of.
The jury is still out on durability.

I created this in OnShape. I've posted the STEP files, or feel free to access the OnShape document [here](https://cad.onshape.com/documents/b57e7d8aa757e68801559d25/v/8cff54a7d572c08c96232f9b/e/661fd476523b613e0589a081?renderMode=0&uiState=678eca670215270177d25429).
