Ultimate "FlexFit" Universal Spool

Say goodbye to cardboard spool problems! Say goodbye to respooling messes, say goodbye to electrical tape, caps, and 500 different spools you need to store and sort through when you buy a new brand of filament that comes on a cardboard roll. This spool is designed to be the exact same size as the Bambu spools so it fits perfectly in the AMS and allows the unit to close properly helping to keep your filament dry. It prints in 3 pieces. 2 sides are exactly the same (so print 2 of them) and have a threaded end and a swappable center adapter to perfectly fit the inside of any cardboard spool that corresponds to it's size. I am making and adding adjusted center adapter sizes as I come across different cardboard spools. How does it work? Gently rip off the side of any cardboard spool. This takes next to no effort on the cardboard spools. Clean up the loose cardboard with your hands so you have your center hole exposed.
