About this model

Updated Jul 19, 2015: I added 2 new stl files to this - labeled as v2. They allow the bracket to be used closer to the frame of the Kossel and there is a much longer arm that allows the spool holder to rest on the back of the Kossel and only utilize one extension bracket (the longer one).. These are extension arms built for a 2020 extrusion Kossel to be used with this thing (Emmet's gear bearing spool holder). This is made for a larger Kossel with 280mm long horizontal extrusions or larger. Mine are 300mm wide (FolgerTech Kossel) and it works like a charm. These extension arms will extend approx 50mm in length.
