Classroom Models: How They Work

"Unit" atoms come with multiple holes that can be configured for different geometries. In the image below, you can see the various holes & "pegs" that are used. The atom spheres come in halves which need to be opened up to insert radial pegs.

With this design, you can create any standard VSEPR geometry or create Brevais lattices.
