The widespread establishment of maker spaces in schools, community centers, and libraries offers an opportunity to develop Computer-Assisted Design (CAD) models that can be manufactured for science, mathematics, and engineering education courses. The Educational CAD Model Library provides a site for curated, peer-reviewed educational models.
