The painter pole (extension pole) ram mount creates and B size ball on the end of a paint/extension pole. This adapters allows you to mount different types of objects to the end of a paint pole. I use it for low elevation overhead photography for those locations where flying a drone is not allowed. The threads are tight but break-in with use. Make sure you understand your print setting and make sure it's strong enough to safely carry whatever is attached to it. You don't want to drop your $400 GoPro, or worse. I've wrapped the ball in electricians tape to make it more grippy. Some sort of Plasti-Dip type product might also work. The "Painter pole ram mount.1.2" file has a 1.2" deep socket while the other file is 1.0 inches deep. Not all paint pole threads are the same so I made two versions. The short version is shown in the pictures.
