Summary

A filament clip designed to stay looped around your filament, so you can just leave it hanging on your filament while printing. Just feed one loop of filament through the big closed hole, and use the clip to clip it to itself. 'Modular' because it has numbers on it for those of you (like me) whose slicers don't have enough custom settings to remember what temperature all your filaments are supposed to print at. Just get your filament dialed in, print the numbers corresponding to the temperature you find, and arrange them on the filament accordingly.
