We describe the benefits and logistics of a promising recent technology, 3D printing, that can benefit visually impaired students. The use of 3D printable designs shared as open educational resources can increase accessibility in the higher education classroom, even for instructors who have no interest in designing tactile learning aids themselves. The technology allows for incremental, iterative improvement and customization. For examples, we describe our experience using a 3D printed learning object in an introductory statistics course with a blind student, and we also describe our experience teaching an interdisciplinary service-learning course in which student teams worked with visually impaired individuals to design new 3D printable educational models.
