Filament clip

thingiverse

Just a simple clip to hold the filament on the spool. There are many out there, but mine has one unique feature: the tunnel through which the filament passes is slightly curved, preventing it from coming loose on its own. This clip fits neatly onto spools with walls that range from 3.0mm (BQ) thick to 4.4mm (Esun). Please note that this clip is designed specifically for filaments with a diameter of Ø1.75mm.
