Filament Management System

I strongly advise using PETG or ABS for the hangar due to its high-stress nature. For added strength, I chose PLA for the rollers and paired them with 608 bearings. The threaded rod used is a sturdy 5/16 inch model easily found at most hardware stores, along with its metric equivalent. Three hangars and a 24-inch threaded rod can effortlessly support four spools of filament without any issues arising. However, to prevent tangles, you'll need to develop or acquire a system for routing the filament down to your extruder. I designed the unique hangar in Tinkercad while modifying an existing design called "SBOLT." Unfortunately, I couldn't find the original creator's work to provide proper credit. The bearings used are from a bulk pack purchased on Aliexpress.
