The spool of stock filament I bought with my Anycubic Kobra Max printer did not fit on the spool holder. This adapter is meant to make it fit better so it moves more easily. Its a simple way to reduce how much the spool bounces around on retraction.
It is meant to make a spool with a 75mm inner diameter fit easily on a spool holder with a 40mm spool retainer. I gave it an extra 2mm of space to both the ID and OD so it wouldn't print too big, but you might want to print it at slightly higher than 100% scale.
