Z16 CNC Aluminum Folding Arm Joint for Drone Frames

Folding arms are a genuine convenience for transporting a build without disassembling it, but most folding-joint hardware is sized for the thicker arm tubes typical of larger frames, leaving smaller-tube builds without a good fit. This Z16 joint is machined specifically for that slimmer tube diameter, bringing the same fold-for-transport convenience to more compact builds that a Z30-class joint would be oversized for.
