simple Filament clip

This is a clip to attach the filament to the filament roll so that the filament does not unroll. There are often too few holes in the filament roll so that the protruding filament is either too long or too short to be fixed well enough in the holes. The clip fits many common filament rolls and is available here for 1.75 mm and 2.85 mm filament.Recommended material to use is PETG or TPU.
