About this model
This CO2 molecule 3D model shows carbon dioxide exactly as chemistry teachers build it with a molecular kit. A dark charcoal carbon atom sits in the middle, flanked by two red oxygen atoms in a perfectly straight line at 180 degrees. Each carbon to oxygen double bond is made of two parallel light grey sticks stacked above each other, so the bond order reads clearly from the front. Below the carbon, a slim steel post leads down into the rounded lilac base shared by the whole lab set. All parts are fused into a single watertight mesh and carry clean baked textures without wear. Use it for greenhouse gas explainers, climate infographics or a lab shelf. It measures 11.2 cm across and 9 cm in height and uses 6,560 triangles with 2K PBR maps.
Good for
- Greenhouse gas and climate infographics
- Chemistry class illustration
- Science museum or exhibit scene
- Environmental education game

Engine import notes
Unity GLB · FBX
Import the GLB with the glTFast package or use the FBX. 1 m in the file = 1 Unity unit.
Unreal Engine FBX
Use the FBX. The model is built in metres. Unreal works in centimetres and converts on import, so it arrives at real size (0.09 m = 9 cm).
Godot 4 GLB · FBX
Drag the GLB into the FileSystem dock. Godot 4 imports it directly, with materials. The FBX works too (Godot 4.3+ imports it natively).
Blender BLEND · GLB
Open the .blend directly, or import the GLB via File › Import › glTF 2.0.
