Customizable Chloroform (CHCl3) - Labeled 3D Molecule Model

Labeled ball-and-stick 3D model of Chloroform (CHCl3, trichloromethane) - customizable in TrueGeometry Playground.

CHEMISTRY

Chloroform is one carbon, one hydrogen and three chlorines arranged tetrahedrally around the carbon. A classic solvent, once used as an anesthetic, now mainly a laboratory/industrial solvent and PTFE precursor. Hazardous in real life - this model is the safe way to handle it. Atom positions, connectivity and bond orders come from the PubChem 3D record (CID 6212):

LABELED ATOMS

Every atom carries its element symbol plus a sub-line naming its most-common isotope with proton and neutron counts (chlorine: 35 P-17 N-18, carbon: 12 P-6 N-6, hydrogen: 1 P-1 N-0). The labels are extruded text geometry and are part of the STL export (verified: the export triangle count matches the scene meshes exactly).

CUSTOMIZABLE IN TRUEGEOMETRY PLAYGROUND

Three sliders: $ATOM atom size, $BONDR bond-stick radius, $BONDL bond length. Run the recipe in the free Playground (tick Auto-Run, then drag the sliders):

COVER IMAGE NOTE

The cover image shows the model at the $ATOM 12 / $BONDL 34 hero preset (smaller atoms, longer sticks) for readability. The attached STL is the default build ($ATOM 17, $BONDL 28).

PRINTING

Display and education model. The bond sticks intersect the atom spheres by design (separate overlapping shells, not unioned), so slicers that require a single manifold shell may need a union/boolean pass first. Fine label plates and thin sticks may need a 0.2 mm nozzle or resin at small slider values. Not test-printed - if you print one, please share a Make to help the community!

The attached STL (2-chloroform.stl) is a native Playground export of the default build (20,548 triangles). The attached PDF is a how-to guide for running TrueGeometry Playground recipes.
