Summary

Similar to a cable management system, this threader is a loop to mount on a shelf or edge of a desk to help guide your filament. When I print with only one extruder on my Dreamer, I found that the back and forth motion could cause a sawing effect where the filament from the unused extruder was rubbing against the edge of the desk shelf. So, the curved surface of the threader prevents that.

Since I mount my filament reels under the desk the threader also prevents me having to fish for the loose end constantly through the gap in the back of the desk.

There are two files; a single threader and a "fiver."
