Oleamide, C₁₈H₃₅NO, 301-02-0, 3D Oleamide to print

Oleamide (C18H35NO, CAS 301-02-0) — a free educational 3D molecular model for teachers and students, by MolGod.org. Instead of colour coding, every sphere carries its engraved element symbol. Colour keys break down in 3D printing, because an STL holds geometry alone and most classroom printers use one filament at a time. The MolGod approach puts the information where students look for it, on the atom: every sphere is engraved with its symbol. Our goal is to let students understand on their own how the atoms are arranged, how they are bonded and what the 3D geometry looks like, straight from the model in their hands. Instead of building a model from scratch, a teacher can go straight from the molecule's name to a file in the slicer. Curious about the science behind the engraving? The project page is at How the engraved atom letters are designed. Oleamide is a chain molecule with no ring: 54 bonds (52 single and 2 double) connect its 55 atoms. Hand the model round and let students tally the engraved atoms: 18 C + 35 H + 1 N + 1 O, 55 in total. Where on the model can students see the amide group (-CO-N<) and the carbon-carbon double bond (C=C)? Let them search before you reveal the answer. A good fit for lessons on the carbonyl group (C=O). Want a comparison? The most similar structures in the MolGod.org collection are Docosanamide (CAS 3061-75-4) and Stearic acid amide (CAS 124-26-5). MolGod.org shares these models for free to make chemistry tangible in the classroom. Teachers: the engraved symbols let students work with the model without a separate key. The model is yours to download, print and teach with. When you publish a photo, a worksheet or a remix, CC BY-SA 4.0 requires you to credit "MolGod.org" as the author of the model, link to the original and to the licence, indicate any changes and share remixes under the same licence (the ready attribution line is below). Nothing else is needed: no account, no cost, no compulsory feedback. Your opinion really matters to us: post a comment with your review, your print photos or your classroom ideas, and tell us how to improve our educational molecules. Contact: Write to the MolGod team. Feel free to discuss the model here, compare notes with other educators, or contact us; every conversation helps us build better teaching models. Missing a compound for your lesson?

STL mesh: 595,748 triangles, closed (watertight) single solid. Coordinates in ångström (STL stores no unit) — scale the model deliberately in your slicer.
