Robust Filament spool clip

I designed this thicker than average spool clip because I was tired of clips breaking or falling off easily. Unlike thin or flimsy clips, this clip is intentionally reinforced to handle stiffer filaments and frequent use. The smooth curved hook guides filament safely into place while preventing tangles, unraveling, or accidental spool explosions. It snaps on easily and stays put, even on tightly wound spools.
