A simple ball head for a tripod. There are two versions of the body part, one with a 3/8 thread and one with a 1/4 thread. I am using a screw in thread adaptor as a kind of metal thread insert, it came free with the gorilla pod so why not. It works with medium sized camera and small lens. There is too much friction on turning the big grip wheel to be able to really clamp down on ball. I will iterate some more and update when I have time but thought I would share my first working version.
