**Just another filament spool**. I created this spool because I was unsatisfied with the stock bambu spools and the other options available. It fits the BBL refills and has a threaded desiccant box to go in the center. It fastens with a triple start thread that only requires a ¾ turn to fully seat it. Ensure it is fully seated before you remove the filament bands so your spool doesn't get all loosey goosey. It also has a 3mm keyway in case I ever feel the need for a filament winder. Enjoy.
