Spool adapter ring for Elegoo Cardboard spools like on the Rapid PETG cardboard spools to allow use in Bambu Lab AMS.

Pegs in adapter help hold ring in place as spool spins. Ribs on edges help grip the AMS rollers.

Flat section of inner ring goes to top of spool. Filament manufacturer label on inside of adapter.

Please let me know if you have any suggestions.
