thingiverse

This Y adapter/piece/part is designed specifically for the 3Dator 3D printer. With minimal modifications and a few adjustments to the Marlin firmware, it should function with other bowden printers as well. The mechanism is straightforward. One filament is printed using one extruder. On Toolchange, the filament is retracted until the other material can be fed into the hotend.
