Filament reel

This is a custom reel holder designed for the Ultimaker range of printers. The goal was to create one that can feed directly into a direct drive extruder without excessive friction. Check out the photos below. I printed this prototype using 100% infill, but you may be able to get away with less material depending on your specific needs.
