1,4-Butane sultone, C₄H₈O₃S, 1633-83-6, 3D 1,4-Butane sultone to print

1,4-Butane sultone (C4H8O3S, CAS 1633-83-6) — a free educational 3D molecular model for teachers and students, by MolGod.org. No legend required: the element symbol is engraved on each atom. An STL file stores shape only, never colour, so a printed ball-and-stick model usually gives no clue which sphere is which element. 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. Teachers get the structure and its atom labels in a single download, which removes the slowest steps before a classroom print. Curious about the science behind the engraving? The project page is at How the engraved atom letters are designed. At its heart, 1,4-Butane sultone is built around one 6-membered ring. The model shows 16 bonds: 14 single and 2 double. Students work from the model back to the formula C4H8O3S: the symbol count is 4 C + 8 H + 3 O + 1 S, or 16 atoms all told. Ask the class to judge by eye the angles at a few carbon atoms: all carbons are sp3, so each should look tetrahedral. On paper the molecule offers 0 donors and 3 acceptors for hydrogen bonding (computed); ask students which atoms they expect to take part. MolGod.org builds and releases these models at no cost for chemistry teaching. Teachers: use it as a hands-on starter before drawing the structural formula on the board. Download it, print it and use it in your teaching. 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. You don't need an account, you don't pay anything, and a review is entirely up to you. Your comments decide what we improve next, from engraving depth to which molecules we add.

All we need is a CAS number: from it MolGod generates the 3D structure, engraves every atom and prepares the STL.
