Cyclohexane (C6H12, CAS 110-82-7) — a free educational 3D molecular model for teachers and students, by MolGod.org. Each atom is labelled with its own engraved element symbol: no colour chart needed.
Which rings can the class see in Cyclohexane? The answer is one 6-membered ring, joined up by 18 bonds altogether (all of them single). Use the engraved letters like a register: call out each element and tick it off until the class reaches 6 C + 12 H (18 atoms altogether). Plan it into a unit on cycloalkanes (saturated carbon rings) and tetrahedral (sp3) carbon. Ask the class why this molecule cannot hydrogen-bond to itself: the computed count of donors and acceptors is zero. Fully sp3 carbon framework: a straightforward model for tetrahedral geometry.
MolGod.org offers this engraved model free to anyone teaching or learning chemistry. Teachers: use the model for an exit-ticket question on the structure the class has just studied.

A ball-and-stick model of Cyclohexane with each element symbol recessed into its atom sphere, generated by MolGod.org from a PubChem-computed 3D conformer (not an experimental crystal structure); atomic coordinates and connectivity are unchanged. STL mesh: 188,176 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
Names in other languages: Cyclohexan (de); cicloesano (it); cyclohexaan (nl); cykloheksan (pl); 环己烷 (zh).
