Warfarin (C19H16O4, CAS 81-81-2) — a free educational 3D molecular model for teachers and students, by MolGod.org. Element symbols are cut into each atom sphere: a self-labelled teaching aid.
Turn the model in your hand to see the shape of Warfarin: three 6-membered rings, with one pair of rings fused along a shared edge, two of them aromatic, and 41 bonds in total (27 single, 3 double and 11 aromatic, drawn in Kekulé form). Hand the model round and let students tally the engraved atoms: 19 C + 16 H + 4 O, 39 in total. No R/S label is assigned here, although Warfarin contains one stereocentre: ask the class which arrangements are possible. Students meeting aromaticity and delocalised electrons, chirality, enantiomers and CIP (R/S) rules, fused ring systems, the carbonyl group (C=O), as well as phenols and hydrogen bonding for the first time can hold an example in their hands. Spot-the-group challenge: can students find the ketone group (C=O) and the phenolic hydroxyl group (Ar-OH)?
MolGod.org offers this engraved model free to anyone teaching or learning chemistry. Teachers: use it as a hands-on starter before drawing the structural formula on the board.

A ball-and-stick model of Warfarin 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: 507,486 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
