Customizable Labeled Molecules - Acids, Solvents and Aromatics Set (Methanol, Chloroform, Nitric Acid, Sulfuric Acid, Toluene, Benzaldehyde, Naphthalene, Vanillin)

DOWNLOADS IN THIS LISTING: the complete set bundle - all 8 native STL exports (one per molecule; unprinted and untested), the 8 full Playground recipes, and the how-to-run guide PDF. Printability caveat: bond sticks and label plates deliberately overlap the atom spheres, and these native exports have not been checked for manifold correctness or sliced - inspect and repair the mesh in your slicer before printing. Each molecule's individual listing (linked below) has its own presets, photos and guide.

A set of 8 labeled ball-and-stick molecule models - two common acids, two solvents and four aromatic/organic molecules: Methanol (CH3OH), Chloroform (CHCl3), Nitric acid (HNO3), Sulfuric acid (H2SO4), Toluene (C7H8), Benzaldehyde (C7H6O), Naphthalene (C10H8), Vanillin (C8H8O3).

Every atom is a sphere in standard CPK colors with its element symbol plus the most-common isotope's mass, proton and neutron counts as real geometry ON the sphere (e.g. O / 16 P-8 N-8), and every bond is a separate stick. Built natively in TrueGeometry Playground - no booleans; bond sticks and label plates overlap the spheres by design.

CUSTOMIZABLE: each model is generated from a variable-first Playground recipe with $ATOM (atom size), $BONDR (stick radius) and $BONDL (bond length) as Live Parameters sliders at the top of the panel - drag the sliders to restyle the model, then export your own STL. The 8 full recipes and a how-to-run guide PDF are attached.

Printing: display/education models - atoms, sticks and label plates overlap by design (no unions), so slice with default settings (merge overlapping volumes). Small labels may need a 0.2 mm nozzle or scaling up for crisp text. Not yet test-printed by us - if you print one, please post a Make and help the community.
