Twisting the male plug to the left pulls it into the locking detents, making it ideal for specialized rotary applications or setups where standard clockwise torque would accidentally loosen the joint. A robust, positive-locking bayonet / twist-lock mechanism designed specifically for functional 3D prints, custom enclosures, modular mounts, and utility fixtures.
