Custom-Printed 3D Models for Teaching Molecular Symmetry

Models were prepared by 3D printing that can be used to demonstrate the operations required for the study of molecular symmetry. The models were designed to emphasize the order and locations of rotation axes and to clearly illustrate the more abstract reflection and improper rotation axes. The models were well-received by students in a course on molecular structure, who generally felt that their understanding of the topic was enhanced by using the models.
