This is a parametric replacement handle release button / actuator bar designed for telescoping luggage handles (e.g. common Samsonite/American Tourister–style mechanisms).

I originally modeled this to replace a broken internal plastic actuator where the original part had cracked, causing the handle pins to stop retracting. The design is fully printable on consumer FDM printers and tuned for strength and durability. This happened to me on three different suitcases of different brands so I figured I'd make a parametric version since they're all, at their core, the same mechanisms, just different lengths.

As a side note, adding text or branding to it makes it easy to distinguish your luggage at the carrousel without adding a protruding tag that can fall off or be removed.
