Filament Management System
thingiverse
I reccomend using PETG or ABS for the hangar. Strength is important as its a stressed part. I made the rollers with PLA and 608 bearings. The rod is a threaded rod.5/16 available at most hardware stores (or its metric equivalent). The shelves they are hanging from are 'Closetmaid' wire shelves from Home Depot. 3 hangars and a 24" threaded rod can hang 4 spools of filament without issue. You will need to cook up some way to manage/route the filament down to your extruder to prevent tangles. I will be rebuilding the workbench below this shelf, and there the printer shall live. the part called "SBOLT" is actually a slight remix of somebody else' excellent work. However, I cant find their original thing to give credit. The weird hangar is my own design, done in Tinkercad. Bearings bought as a bulk pack from Aliexpress.
