3D Hubs, like MakeXYZ, was a community-based 3D printing service that let anyone with a printer sell their prints online. Founded in the heyday of the 3D printing revolution, the service let thousands of makers gather a little cash for making and mailing prints on their home 3D printers.

Now, however, the company has moved to a model in which its high-end partners will be manufacturing plastic, metal, and injection molded parts for customers willing to pay extra for a professional print.
