Selling to purchase a new 3D printer. The degree of dirtiness is as shown in the photos. It will get dirty sooner or later, but please refrain from purchasing if you are concerned. The operation is not a problem. The part to hold the lid is missing. The handle of the resin tank is also missing. I removed it because it was in the way and used it without it. It has a heater. Everything in the photos is included. I think it's best to assume that there are no spare screws or other small accessories. (Items other than the printer are not included.) I plan to wrap it in bubble wrap and then wrap it in corrugated cardboard for shipping.
