Filament spool rail

This base can be used to create a rail-type rack for filament spools.Just print 2 or more bases and stick them with 3M tape to some aluminium profiles. If the rail is longer than 1m I would recommend having extra bases in the middle.PLA should be a decent choice, but I opted for PETG, because it should experience less material creep. Also, triangles infill would be a great choice due to its better stiffness.The bill of materials for this build would be:2 30x30mm L type aluminium profiles3M tape for securing everything together
