Dremel 3D20 Filament Holder

thingiverse

This spool holder fits over the top of the Dremel 3D20 and allows the use of most larger 1 kg filament spools. The design was modified from a version found on GrabCAD (https://grabcad.com/library/dremel-3d20-filament-spool-holder-1) and could still benefit from improvements. A key modification made was adding a keeper to the end of the axle, which wasn't present in the original design. The main arm was also repositioned on the printer to save filament, but it remains very strong and can hold heavier spools with ease due to its larger axle piece. The original design mounted on the left side of the back of the printer and included a separate filament guide that mounted on the right side. However, mounting the holder on the right side eliminates the need for an additional guide.
