608ZZ Printable bearing. Used with https://www.thingiverse.com/thing:3209211 in my example. My filament with real bearings would freespin and tangle the filament around the spool. Since printed bearings are a little more restrictive, this is perfect for this application.
Support is included in print. There is a ring around the bearings, print with that side down.
Remove after printing, work bearing for a decent bit.
If you need more clearance, let me know, via comment.
