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.
