Spool Clip for Matter Hacker 1.75 dia PLA and ProtoPasta 1.75 PLA

A simple "Spool Clip" to keep filament from unwinding. Printed in PLA and PETG. Both work well with the brand of filament spools mentioned. As the filament level decreases it may be necessary to pull the open ends of the clips together in some manner. There is adequate material on the open ends to accommodate drilling holes to run elastic tensioners with spring clips on the ends -similar to what you find on your jacket to tighten things up around your waist. Haven't needed to do this yet- works
