Bayonet Twist-Lock Quick-Change Mount
A two-piece bayonet coupler that prints as one captive assembly: drop-in plug, twist 60° and three keys lock under the socket lip, past a detent bump and into a hard stop. Socket flange is 68 mm square with M4 clearance holes on a 56 mm square (14 mm tall); the 40 mm plug disc takes M4 on a 22 mm square, with a 20 mm centre pass-through for cable or a shaft — for swapping lights, sensor pods, cameras or tool heads off a fixed base.
