About this model
A DNA helix 3d model in the style of a classroom ball and stick kit. Two full turns climb around a slim chrome centre rod, with twenty base pairs set at 36 degree steps just like the real B form. One backbone strand is light blue, the other soft pink, and a round node marks every place where a base pair docks. Each rung is split in the middle into two colours, yellow with mint and lilac with peach, which stand for the two possible pairings without any letters. A grey ball caps the rod, and the round white base shows a small heart with a heartbeat trace, the symbol shared by all pieces of the Cozy Hospital & Medical Kit. The model is 45 cm tall with a 16 cm base and has 15,268 triangles. Unlike the floating DNA Double Helix, this is a desk model for labs, schools and genetics scenes.
Good for
- Genetics lab or biology classroom
- Science fair or museum display
- Educational game about cells
- Desk decoration in a research office

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 (0.45 m = 45 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.
