3Dator Y-piece for dual extrusion with one nozzle

thingiverse

This y adapter/piece/part is made for the 3Dator 3D printer. With minor modifications and a few changes in the Marlin firmware it should work with other bowden printers too. The mechanism is pretty straight forward. One Filament is printed with one of the extruders. On Toolchange the filament is retracted till the other material can be driven into the hotend. We made a video for you to see it in action:https://www.youtube.com/watch?v=hvh5HKj31QA For more detailed information have a look into our wiki:http://wiki.3dator.com/index.php/Dual_Extruder_single_nozzle/en If you already own one of our printers feel free to buy our extension set with all parts that are needed.
