Meet the ultimate spool upgrade! Designed with practicality in mind, this stackable spool saves space when not in use. Featuring built-in filament clips (4 on each side), it keeps your filament secure and prevents rolling. Best of all, it’s reversible—no need to worry about matching sides, any two pieces work together seamlessly. Lightweight and quick to print (under 2 hours and 60g filament), it’s the efficient solution every maker needs.
