After mentoring a 3D printing project to create maps for visually impaired students two years ago, which involved two teachers and a group of students from Pasadena City College, MIT alumna Joan Horvath and open-source 3D printer hacker Rich Cameron have created a project to help these teachers get educational 3D models. Their project, which was named as a semifinalist in the 2016 Hackaday Prize competition, consists of a Google Group that allows teachers to request different educational 3D models to help teach the visually impaired. These requests are then met by other students looking to learn about 3D design or 3D printing. To demonstrate the potential of their open-source community-based project, Horvath and Cameron fulfilled one request to design different shapes with the same volume, which allowed the teachers to demonstrate to their visually impaired students that the objects had the same inner volume.
