Carbon dioxide

Carbon Dioxide (CO₂) — Space-Fill Molecular Model

A chemically accurate, 3D-printable space-fill model of carbon dioxide — perfect for science classrooms, desk displays, chemistry enthusiasts, or anyone who wants to hold a greenhouse gas in their hand.

About the molecule CO₂ is a linear triatomic molecule: two oxygen atoms doubly bonded to a central carbon atom at a perfect 180°. This model captures that iconic straight-line geometry using proportional Van der Waals radii — the same approach used in professional molecular visualisation.

Great for

• STEM education and school science displays
• Chemistry desk decor
• Climate and atmospheric science projects
• Molecular model collections (pairs well with H₂O, O₃, N₂, CH₄)

If you remix this model, please credit the original and share your colour choices — would love to see your take on CPK vs. Corey–Pauling!
