The file 'Filament Clip, Filament Keeper, Filament Holder 3D Printer Model' is (stl) file type, size is 6.3KB.
I have tried most all of the "free" filament clips and none would sufficiently hold my filament. The following design is based on a similar clip that I received with a spool of filament, so I tried to duplicate it's main attributes, which would securely hold 1.75 mm filament to the edge of the spool. Hope it works for you.
UPDATE Added "SmallFilamentClip.stl" file, which is the same filament clip with a smaller gap, so it will fit spools with thinner sidewalls. Let me know how it works.
