1. A method of printing an object with a three-dimensional printer, the method comprising: identifying a first data file that includes first dimensions that may be used by the three-dimensional printer to form a physical three-dimensional model of a first object; identifying a second data file that includes second dimensions that may be used by a three-dimensional printer to form a physical three-dimensional model of a second object; determining a proportionality factor between the first dimensions and the second dimensions, wherein the proportionality factor includes a fraction or percentage increase or decrease in the second dimensions; multiplying the second dimensions in the second data file by the proportionality factor; and causing the three-dimensional printer to form a physical three-dimensional model of the second object using a product of the multiplication of the second dimensions.
