Sunlu OLD spool insert holder for RFID tag

This little Sunlu spool adapter does 2 things- It adds a small amount of weight to your spool to possibly keep it from bouncing around and theres a convenient little notch where you can glue in the old RFID tag from an empty Bambu filament refill. Make sure to bend the tags inwards towards the inside of the adapter to keep them from sticking out directly. If the weight part is important to you, you can change both the infill and wall overlap and get the weight up to 66g. I intent to print them in same color as the spool they came from so that the adapters are easily identifiable. A green insert for the RFID that came off a green spool.
