Filament clips are annoying. They're always popping off when I take spools out or put them back to store them. I wanted something different, completely contained within the spool. I know some of these exist already, but I wanted something easy, efficient, and that wouldn't crimp or clamp my filament. So, I made this. This version fits Overture spools. Versions for other spools currently include Bambu Labs and Elagoo. Other versions coming soon.
