A customizable, labeled ball-and-stick 3D model of toluene (C7H8) - methylbenzene, the classic aromatic solvent - built entirely from native TrueGeometry Playground commands.
CUSTOMIZE IT LIVE
Three sliders in the Playground reader control atom size ($ATOM), bond-stick radius ($BONDR) and bond length ($BONDL). Drag a slider or type a value and the model rebuilds. Run the attached recipe (5-toluene.txt) in the TrueGeometry Playground. Open it in the Playground: https://www.truegeometry.com/CoreWebGLTG/KBEAgentHTTP.html
ABOUT THIS MODEL
- 15 atoms, 18 bond sticks - the aromatic ring is drawn in its Kekule form: the three formal C=C bonds appear as twin pairs of sticks, the classic ball-and-stick convention. The methyl carbon carries three hydrogens.
- Every atom carries an extruded on-sphere label: element symbol plus a sub-line naming the most-common isotope (mass, protons, neutrons - e.g. carbon "12 P-6 N-6"). Labels are included in the STL export.
- Geometry, connectivity and bond orders from PubChem CID 1140. Verified bond directions and connectivity.
NOTE ON THE COVER IMAGE
The cover/hero image shows the model at the smaller-atom "hero" preset ($ATOM 12, $BONDL 34) to expose the bond structure. The STL in Files is the default preset ($ATOM 17, $BONDR 2.6, $BONDL 28) - larger atoms, shorter sticks. Set the sliders to either look in the Playground.

PRINTING NOTES
Not test-printed yet. At the default preset some atoms overlap their neighbors slightly by design (compact molecular look); the hero preset separates them more. 0.2 mm layer height suggested. The attached molecule-guide.pdf covers general printing and customization guidance for this molecule series.
