Methanol (CH4O, CAS 67-56-1) — a free educational 3D molecular model for teachers and students, by MolGod.org. Instead of colour coding, every sphere carries its engraved element symbol.
Methanol is a chain molecule with no ring: 5 bonds (all of them single) connect its 6 atoms. Counting task: 1 C + 4 H + 1 O gives 6 engraved spheres; can the class rebuild the formula CH4O from the model alone? Plan it into a unit on alcohols and hydrogen bonding. Computed hydrogen-bonding profile: 1 donor against 1 acceptor, a starting point for talking about attraction between molecules. Name-and-locate exercise: students touch the hydroxyl group (-OH) and afterwards write the name of every group they touched.
MolGod.org builds and releases these models at no cost for chemistry teaching. Teachers: the engraved symbols let students work with the model without a separate key.

A ball-and-stick model of Methanol 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: 67,568 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
Names in other languages: méthanol (fr); metanolo (it); metanol (pl); 甲醇 (zh).
