1. A method comprising: integrating a first 3D object model with a second 3D object model to generate an integrated 3D printable model, the first 3D object model modeling a first object that is passive, the second 3D object model modeling an electrical power source receptacle that operably connects to an electrical power source that provides electrical power for operation of the first object, the second 3D object model comprising an electrical pathway from the electrical power source receptacle to an actuator of the 3D object; printing a 3D object, with the actuator as a component, based upon the integrated 3D printable model such that the actuator interacts with the electrical power source to provide the electrical power to the first object; and connecting the actuator to the electrical power source using the electrical pathway.
