The Orbit 68821W molecular model kit includes parts to build triphenylphosphine to show propeller rotation in the C3 point group
The 68821W Orbit Point Group Molecular Model set can build all the point group models listed simultaneously. You can also build the C3 point group with the following sets: the advanced Orbit 68827W Chemistry Structures Molecular Model Set & the 68847W Class Organic-Inorganic Molecular Model set.
Three examples of molecules found in common use in the C3 point group include: chlorphenol red & phenolphthalein. All of the compounds have use as indicators that are pH sensitive.

This model set has the flexibility needed to teach symmetry point groups effectively, as well as modeling metal coordination complexes. Some atoms have holes perpendicular to their main bonds, allowing for modeling H-bonds or electrostatic interactions. Construction-wise, atoms pieces are smaller relative to the bond pieces, emphasizing the relative space taken up by orbitals compared to nuclei. However, this can also make it difficult to change molecular structure quickly. Indigo Instruments customer service was also very helpful in processing my order quickly and completing forms required by my institution for requisition.
Thanks for the feedback. It is an unusual set & the only one we know of that can build ferrocene.
