We discovered that if we just let the filament go “sproing” after we removed it from the printers that the filament could get tangled. The problem is that reinstalling a tangled roll can lead to the extrusion stopping mid print. Then you have a half-finished print that is most likely useless. Thus was born our filament clips. We downloaded a couple from Thingiverse, but they didn’t really do the job for us. Below is a link to download our solution for the Afinia filament that we use.

I also have a design for the Premium Afinia filament as well. Just email answers@WRI3D.com.
