Cyclohexyl methacrylate 3D Molecular Model — CAS 101-43-9

Cyclohexyl methacrylate (C10H16O2, CAS 101-43-9) — a free educational 3D molecular model for teachers and students, by MolGod.org. Every sphere shows which element it is through an engraved symbol, not a colour code.

Plain ball-and-stick prints look the same for every element: the STL format has no way to say which ball is carbon and which is oxygen. Our answer is to cut each element symbol into its sphere, so the printed object labels itself in any colour of filament. Our intended outcome is simple: students who hold the model should know each atom immediately and use the lesson to understand the molecule's structure. It shortens the path from lesson plan to printed model, because no one has to build the molecule or add labels by hand. Background, references and the planned classroom study: https://molgod.org/engraved-molecular-models/.

Look at the skeleton first: Cyclohexyl methacrylate contains one 6-membered ring, and students can trace 28 bonds (26 single and 2 double). Give each pair of students the model and a blank sheet: recording every engraved symbol should lead them to 10 C + 16 H + 2 O, which is 28 atoms. Students meeting the carbonyl group (C=O) for the first time can hold an example in their hands. Pair it with Methyl Methacrylate (CAS 80-62-6) and tert-Butyl methacrylate (CAS 25189-00-8) from the same collection to compare closely related structures. On the printed model, students can point to the ester group (-COO-) and the carbon-carbon double bond (C=C).

MolGod.org offers this engraved model free to anyone teaching or learning chemistry. Teachers: pair it with the MolGod.org record to connect the 3D shape with identifiers and data.

Print it, hand it round and build a lesson around it. If you share a photo, a lesson or an adapted version, the licence (CC BY-SA 4.0) asks for credit to "MolGod.org" as the model's author, a link to the original and to the licence text, a note of what you changed, and the same licence for adaptations; the attribution line below is ready to copy. Nothing else is needed: no account, no cost, no compulsory feedback. Help us make better models for students! A comment with your honest review, what worked, what was hard to read, what you would change, is the best gift you can give us. More at https://molgod.org/contact/.

A ball-and-stick model of Cyclohexyl methacrylate 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: 325,874 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
