Simple Universal Filament Clip V2+ {NEW 2024 VERSION}

Filament clip works on many spool brands including Prusament, Amazon Basics, Overature, Hatchbox, AMZ3D and others. Very simple design.

Version 2+, added March 15, 2024 incorporates slightly smaller filament clasps and reverses the two clasps such that the smaller one is closer to the loop and the slightly larger one is closer to the opening.  

Thank you to all who have contributed your suggestions for improvement.  I do read and consider all of them.

Version 2, added on May 4, 2021, incorporates a slightly closer spool clamp with a small spool clamp-side filament holder, and a slightly tighter filament clip with minor adjustments.

Use 4 perimeters and PETG filament for best results.
