Reuse old spool with 54 mm Adaptor (for refill filament)

thingiverse

You can give your old empty spool a second life by using this adapter instead of buying or printing an entire new one. The first time you try it, you might find that the original spool splits unevenly due to the small refill hole. To solve this issue, you'll need to remove the entire center section. Once you've done this, the adapter works smoothly. To make the adapter even more versatile, I've added a new component that allows it to fit the econofil refill perfectly. Additionally, I've included space for securing the tie wrap in place.
