KB3D Switch [Digital STL]

No physical item will be shipped.

Choose the input

The KB3D Switch allows you to alternate between two input sources while maintaining a constant output.

The centre connection remains continuously active, while the left and right inputs can be selected as required—allowing controlled switching between airflow paths without disconnecting your setup.

Built around the NATO40 standard, the Switch integrates seamlessly with KB3D Interface and Air components. It features rotatable connectors, allowing flexible positioning and alignment within more complex systems.
