Roller v2
Description
If you're like me you probably have more 608 bearings than sense. This design puts angular contact on the spool edges so it'll always be aligned and smooth-rolling with no complicated spacing mechanisms. Print two of these and enjoy luxurious, spool-width agnostic, weirdly shaped rolling support. Prints without supports, whatever infill you like. I used 20%, it's really not critical. Overhang is slight, the bearings just need to slide on.
