BallJoint to Tube - Coupling

thingiverse

To attach electronics, like Garmin navigation computers, to bike handlebars using 22mm tubes, follow these instructions. First, obtain an M6 threaded rod. Then cut a thread into the ball provided (with a diameter of 17.5mm) and secure it in place with self-locking nuts. For a smooth finish, polish the ball with wet sandpaper and an electric screwdriver, saving you money in the process.
