About this 3D model

This is a design to print a rhombohedron crystal. Crystallography classes focus to understand and visualize what crystals look like- this print also assists earth science students to understand the symmetry of the crystal. This print is a physical manipulative that can be used to teach the concepts. This is a cheaper alternative, as this kind of crystal model costs upwards of $100 (https://www.miramodus.com/molecular-models/beevers-models/alphabetic-index.shtml).
