GoPro Hero single axis gimbal

So I use a 6' pole to get elevated shots. Problem is the mount is rigid and so the camera angle changes with the angle of the pole. Solution, a single axis free floating gimbal. I printed with 50% infill and 4 perimeters. The pivot point is made for a 8/32 bolt and nut (I use them all day and I don't have any metric). Either leave the nut loose (suggest a lock nut) or do what I did and glue the screws to the inside of the frame, it will not come apart this way unless you pull on the frame wall.
