Easy to print pieces to make a storage rack for your filament! You can make it as long as you want and add support pieces as needed! I used two curtain rods i had laying around and its perfect! The 3mf file is for the middle support. I included the STLs for the end pieces but you could make this just using the support pieces. Only difference is the side pieces don't allow the rod to go all the way though and give it a more finished look IMO.
