Here we have two small but essential components used inside a rail vehicle: a ceiling panel hinge and a safety clamp. The hinge supports and positions the ceiling panel, while the safety clip ensures the panel cannot drop during operation or maintenance. Working together, they provide a simple and reliable way to keep overhead panels safely secured.

Each component measures around 30 mm and weighs roughly 10 g. By leveraging additive manufacturing, the parts could be delivered rapidly and without the need for mould tooling - making them a cost‑effective choice for small‑batch replacements and prototype fit validation.
