Researchers at UCLA and the University of New Mexico say they used 3D printed models of erect penises to determine what women believe is the ideal equipment size for their lovers. And if you're inclined to need to know such things, the women polled seemed more focused on recalling the girth of a model rather than the length. Led by Dr. Nicole Prause, the research team printed 100 different models of erect penises but used just 33 of those options. The models were 3D printed from blue plastic material “to minimize racial skin-color cues” and then placed in baskets. A total of 75 women selected from those options to represent their “ideal penis.” You can read the whole story here: http://3dprint.com/93805/3d-printed-perfect-penis/
