Filament Holder For Sigma Profile

With this accessory you can have a filament holder that will fit in a 20 mm thick sigma profile frame. You can obtain a complete shaft by producing 2 pieces of filament-holder-shaft from stl files consisting of 3 parts in total. You can also make 2 legs with filament - holder - endpoint. You can fix these parts with glue or hot adhesive. It was very functional on my own printer. I am also sending you the freecad files of this design. This way you can tailor it to your own requirements.
