This is a Filament Hanger for a closet/dowel rod that is one-sided and includes a filament clip to help ensure there aren't any tangles.
While there are already other filament hangers, I designed this one because I didn't find a suitable one that was one-sided and didn't require taking apart the hanger to get the filament spool out so I designed my own. It comfortably holds 1 kg spools and smaller spools.
The orientation of the hook can also be changed to your preference. Everything is held together with pressure and friction fits.
The spool uses 58 grams of filament to print and PLA+ is recommended while PLA is still suitable. (Black hangers in picture are PLA+ while white hangers are regular PLA).
There are 2 profiles, one for a single Filament Hanger and one for two at once!
Enjoy organizing and storing your spools!
