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 multiple “center” mounts for solid pipes, longer versions, etc. PrintingPrint on its side, I would recommend at least three perimeters and 20 % infill. (Thats how I printed mine in PETG, they hold up well)I recommend adding tree supports for the screw holes.MountingI highly recommend using screws (diameter 4-6 mm) in combination with washers. This way, the mounting pressure is distributed on a larger area and I don't think that they will ever come off the wall. The srew holes are 6.5 mm in diamet
