Ring Insert (55mm) for Cardboard Spools

Ring Insert (55mm) for Cardboard Spools

prusaprinters

Ring for carboard spools to slip better on spool holder arm.  Make two and press them into your cardboard spools.  I made them specifically for Overture, but will work on any with a 55mm I.D. hole.  Reduces friction and carboard chafing (which made dust all over my enclosure!!).Update - New model added: now with tabs to help retain ring into spool.
