Cyclohexyl methacrylate (CAS 101-43-9): engraved ball-and-stick 3D molecular model (STL)
Abstract
This entry presents Cyclohexyl methacrylate (C10H16O2; CAS 101-43-9; PubChem CID 7561) as a 3D-printable ball-and-stick model in which every atom carries its engraved element symbol (C, H, O), so the model can be read without a colour key. Atomic coordinates come from the PubChem-computed 3D conformer (not an experimental crystal structure); coordinates and connectivity are unchanged. Structure at a glance 28 atoms: 10 C, 16 H, 2 O 28 bonds: 26 single, 2 double One 6-membered ring Functional groups: one ester group (-COO-) and one carbon-carbon double bond (C=C) No hydrogen-bond donors and two acceptors (computed) Fraction of sp3-hybridised (tetrahedral) carbon atoms: 0.7 (computed) Use in teaching Counting task: students tally the engraved symbols (10 C, 16 H, 2 O; 28 atoms) and rebuild the formula C10H16O2 from the model alone. Functional groups: find the ester group (-COO-) and the carbon-carbon double bond (C=C) on the model and name each one. File and printing STL mesh of 325,874 triangles, a closed (watertight) single solid. Coordinates are in ångström and STL stores no unit, so scale the model deliberately in your slicer. Measured bounding box: 7.353 × 6.48 × 5.123 Å; at scale factor 10 (1 Å to 10 mm, file read in millimetres) the print measures about 73.5 × 64.8 × 51.2 mm.
