About this model

5 labeled crystal unit cell models - classic ionic salts and the three metal packing structures every materials science course covers. Every atom is a sphere in standard CPK colors with its element symbol plus proton and neutron counts printed right ON the sphere (e.g. C P-6 N-6), and every bond is a separate stick. Built natively in TrueGeometry Playground - no booleans, overlapping shells only, so slicers merge the parts cleanly. CUSTOMIZABLE: each model is generated from a Playground script with $ATOM (atom size), $BONDR (stick radius) and $BONDL (bond length) as Live Parameters - tick Auto-Run and drag the sliders to restyle the model before exporting your own STL. Full TrueGeometry Playground commands: in the blog article and the attached recipe files. Playground: Included models: NaC…
