Here is a item that came off the 3D printer, an old hit n miss engine. Would look great in your business providing power to your shop or as junk on the side of a building somewhere. Some simple assembly is required. The castings of course are not painted. The figure is not included just for you to see the size of the item. The engine measures 1" by 1 1/4" by 1" tall.
