In order to make a decent holder for my Nexus 7 I'd like to remove the ball at the end of the DJI phone holder. There's a small grub screw which unscrews, but does NOT loosen the ball. Has anyone managed to remove the ball?
Update: the ball fits tightly, but with the grub screw removed it will come loose. See new picture.
