Filament Shelf

This filament shelf is designed to use two hollow aluminum pipes (outer diameter 20 mm, 1 mm wall thickness). The pipes slot into the holders.The files include two holders (left and right) as well as an optional center piece for supporting longer pipes. I used 1 meter pipes and don't need the center support. Fully loaded with 14-15 spools, the pipes hold up well for me.Variants: short: Use only left and right mount (up to 1 m pipe)long: Use left, right and center mount (>1 m pipe)creative: Use m
