Use common 608 bearings

It would be great to use the common 608 bearings instead of the 12mm ID bearings required now. The price and availability are much better.
I modified the stl files myself before printing, but I don't have access to SolidWorks, so I can't contribute updated files. I'd be happy to help otherwise if needed.
Thanks for providing this thing for free!

You can use the .step files for the remixing and later export if for solidworks in e.g. Fusion 360
