Eccentric Cam Panel Draw Connector
This is a two-piece, print-in-place, surface-mount connector that replaces a stripped flat-pack cam lock. It does not need the old cam hole. The 27 mm eccentric cam turns on a #8 (4.2 mm) wood screw driven into panel A. The cam sits captured under a 45° lip in a 72 x 40 x 7 mm keeper, which is screwed to panel B through slotted #8 holes. A half-turn of the cam's 19 mm hex pulls the joint 6 mm tight, and the cam locks past dead centre.
Print-In-Place Cam Lever Rod Clamp
A tool-free quick-release clamp for 8 mm smooth rod: a split C-collar with an 8.3 mm slip-fit bore and two cam lobes, wrapped by a print-in-place cam ring whose 30 mm lever squeezes the jaws shut in about a quarter turn. The 46 x 24 x 5 mm foot bolts down with two M3 screws on 36 mm centres; overall 62 x 24 x 27 mm, so a boom, antenna mast, sensor pole or stop collar can be re-positioned by hand instead of with a hex key.
