51mm Filament Spool Adapter

I'd love to use more material, but it's a perfect fit for nearly every spool I have. Printing 24 of them will definitely make them last a long time. They print relatively slowly, but they're incredibly rugged. My 3/8 inch aluminum rods in my dry boxes fit perfectly inside these spools. The filament brands I use are eSun, Solutech and Filamentum, and they work flawlessly together. Fortunately, these spools don't fit the Taulman mini-spools, which is a minor issue for me. My first contribution to Thingiverse!
