Sunlu Adapter for Bambu AMS Lite

Sunlu (and perhaps others) distributes 1 kg filament spools with a larger I.D. (about 73 mm) than the O.D. (about 54 mm) of the Bambu Lite receiver. Putting the Sunlu spool on the receiver will fall off with use. Placing the adapter through the Sunlu spool and then onto the Bambu receiver will keep it in place. Lateral movement is also prevented by the outer ring of the adapter.
