Customizable Chain Links is a Geometry Nodes setup applied to a curve object, allowing users to draw and control chains by editing curve handles. The modifier provides custom values for adjusting the scale of the chains, the distance between links, and adding random rotation with a seed value.

The system includes 10 different chain link types organized in collections, which can be swapped directly from the modifier interface. Additionally, it comes with 10 procedural metal materials structured as node groups, enabling further customization of the metal appearance.
