I tried several filaments clips but found that many of them is useless and others do not work well. I ran into the best universal dual filament dragon clip. It clips onto the spool of any brand of filament. It clips onto 1.75mm or 2.85mm filament. It is shaped like a dragon hence the name Universal Dual-Filament Dragon Clip.
Why this filament clip? I've always used filament clips that clip to the filament itself, but I was curious to try one that clips to the spool, so I searched Thingiverse for the best one. In my opinion this is the best clip that I have used thus far with e-Sun filament spools. Give this Dual Filament Dragon Clip a try.
Thanks to Lyl3 for making this design available on Thingiverse.
