My first attempt at a spool roller, had some 688ZZ bearings, so this is made for them...seems to work OK...no issues so far, I printed @ 30 microns layer height, as I built a lot of tolerance into it for different printers.
I put little round rubber feet on the bottom to give it good stick to the ground.
hope it works for you
