Grandma's Favorite Filament Clip - Double Lock

Having tested dozens of filament clips over the years, I wasn't happy until I discovered Grandma's Favorite Filament Clip. It was the best clip I had found but wasn't exactly what I needed. My problem was the lack of neatly wound spools. As a result, Grandma's Favorite Filament Clip sat at an angle, sometimes slipping sideways enough that it seemed like it may lose its grip on the filament. From that problem, this remix was born. This double locking remix simply doubles up the original design, back-to-back. A single filament path through the middle is surrounded on both sides by the locking filament path. Using the closed clip as a starting point gives a little extra piece of mind that the filament won't accidentally slip off the clip.
