About this 3D model
Originally posted from the original by philltran - https://www.printables.com/model/339966 - additional steps in italics. Each spool requires one core adapter. Remove the RFID tag from the original Bambu Lab cardboard core that you wish to reuse - make sure to remember which side of the tags face outwards Remove one cardboard sides off of the original spool. Place the spool on a sturdy surface with the open side facing up. Insert the adapter into the center of the spool. Make the edge of the adapter flush with the edge of the cardboard core. The adapter has a slot to line up with the notch on the Bambu reusable spools. Make sure slotted side of the adapter is facing out Add the RFID tag removed earlier through the thin slot - it may be quite tight if some glue remains from the original tag. Fold the tags up to lie flush with the new filament Separate the Bambu reusable spool into two parts. Insert the Bambu spool section with notch onto the spool core so that the notch lines up with the slot on the adapter. Holding the spool together firmly, flip over the spool so that the remaining cardboard side faces up. Remove the remaining cardboard sides off of the spool. Insert the remaining Bambu spool section onto the spool core. Rotate the Bambu reusable spool sections until the two sections “click” together.
