1. A method of creating a replica of an anatomical structure, comprising:
accepting, by a first computer system, a plurality of pictures of the anatomical structure of a subject, each picture of the plurality of pictures from a distinct viewing angle relative to the anatomical structure;
creating, by the first computer system, an object file that contains an initial model of an outside surface of the anatomical structure;
cutting, by the first computer system, the initial model to a predetermined exterior shape circumscribing the anatomical structure, the cutting creates a positive model of the anatomical structure within the predetermined exterior shape;
creating, by the first computer system, a negative model of the anatomical structure from the positive model;
placing, by the first computer system, a stem tool object on an outside surface of the negative model in relationship to an orifice of the anatomical structure;
placing, by the first computer system, a zeroing object and angling object to align the negative model to a predetermined angle;
placing, by the first computer system, a base tool object by coupling the base tool object to the outside surface of the aligned negative model to create a final negative model; and
printing, by way of a three-dimensional printer, the final negative model to create a negative mold; and
casting the replica of the anatomical structure using the negative mold.
