Cinnamaldehyde 3D Molecular Model — CAS 104-55-2

Cinnamaldehyde (C9H8O, CAS 104-55-2) — a free educational 3D molecular model for teachers and students, by MolGod.org. Instead of colour coding, every sphere carries its engraved element symbol. Most printable molecule files rely on colour coding, yet the STL format carries no colour and a single-filament print loses it entirely. We build the label into the model: each sphere bears its recessed element symbol, readable by eye and by fingertip. Our goal as an education project: free files for te…
