I didn't have any spare 608ZZ roller bearings on hand, but I had a number of 6900ZZ roller bearings.
The 608ZZ has an outside dimension of 22mm and an inside dimension of 8mm. The 6900ZZ roller bearings have an outside dimension of 22mm and an inside dimension of 10mm, plus a bearing boss that is 13mm.
So I changed the spool center roller to use 6900ZZ bearings. I did a test slice of one side to test the bearing fit. A snug fit.
You need to use the roller holder from the other model.
