Bench Dog Hole Cam Clamp
A print-in-place eccentric cam clamp that drops into a 3/4 in (19.05 mm) bench dog hole and twists to pin work against a fence or a second dog — 5 mm of cam throw past the 24 mm collar stop, for stock 9 mm thick and up. The 19.2 mm shank is bored and split into two spring tabs so it grips the hole instead of rattling; 41.4 mm tall, 26 mm knob, two pieces printed as one assembly with 0.5 mm clearances (print with a brim, no supports).
