Lightweight SUNLU Spool Adapters

Designed for the Adjustable Spool Holder to be easily and securely used in SUNLU spools (or any spool with up to 72.5 diameter spool ID side). Inner hole dimension is ~50mm to hole silica gel holder, adapter rims are 72.5mm and 73.3mm to securely fit into both sides SUNLU spool.I created this after finding existing adapters using way too much plastic. These print at just over 16g combined and are plenty strong. Recommended to print in PETG but PLA works fine too.
