Filament Spool Rack (bar or brush handle required)
thingiverse
I crafted a rack for spools using reclaimed metal rod, which offered a snug yet stable fit on my pole. For accommodating various diameters, I recommend utilizing Tinkercad since editing STL files in Fusion 360 proves to be a daunting task. When three brackets are employed together, they can effortlessly support an impressive weight of 20 kilograms. To ensure added stability and prevent any potential collapse, I opted for five perimeters and 50% infill density - perhaps overkill, but it's better to err on the side of caution when dealing with my printer.
