This is the extruder for the XYZprinting da Vinci 1.0 Pro 3D printer. The new standard price is around 17,370 yen including tax. I am selling it because I no longer use it. Please consider purchasing only if you understand that this is a used item. There is some slight filament burn around the nozzle, but it does not affect the operation (it can be removed by polishing if you are concerned).
