Dimorpholinomethane (C9H18N2O2, CAS 5625-90-1) — 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.
Ask students to describe the framework of Dimorpholinomethane before anything else: two 6-membered rings. Then count the bonds together; there are 32 (all of them single). Give each pair of students the model and a blank sheet: recording every engraved symbol should lead them to 9 C + 18 H + 2 N + 2 O, which is 31 atoms. Where on the model can students see the two ether linkages (C-O-C) and the two tertiary amino groups (-NR2)? Let them search before you reveal the answer. Lesson link: amines and basicity. Natural follow-up models: Dtdm (CAS 103-34-4) and 1,4-dioxane (CAS 123-91-1), close enough in structure for a spot-the-difference task.
Part of the MolGod.org free library of engraved molecules for chemistry classrooms. Teachers: use it as a hands-on starter before drawing the structural formula on the board.

A ball-and-stick model of Dimorpholinomethane 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: 346,690 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
Names in other languages: Bis(morpholino)methan (de).
