Filament spool box

pinshape

Hi I've developed a filament spool case that fits a standard 800g filament roll. The benefit is that the filament can't jump off the roll when printing or pushing back. This is very crucial for my planned bowden feeding because I don't always want to open the filament box. Also, attention was paid to minimizing space loss so that six colors fit into a small filament box. But more on this later... You need: Printed parts Aluminium tube outer diameter 10 mm; wall thickness 1.5 mm ( length depending on filament spool width ) Ball bearings standard 22/8/7 Screws 4x60/34 ( e.g. Würth assembly Art. 0170 14060 ) Happy printing!
