Window camera/spotting scope mount for metallic screw

thingiverse

This is a modification to an existing design which conceptually worked well, but relied on a ball with integrated, printed, 1/4 x 20 screw for attaching to the spotting scope. This does, especially if printed in the provided position, introduce point of failure, as it may snap along print surface and result in a $500+ spotting scope dropped 5' onto the road. This modification replaces the 1/4x20 screw with a 6mm through hole. After the ball is printed, it is threaded with 1/4x20 tap, and then a piece of 1/4x20 threaded rod (easily manufactured by simply cutting of some ~25mm from a a 1/4x20 bolt) is run through the ball, extruding ~5mm on the top. This is a little more work than the original design but will not fail under any reasonable circumstance. I also shrunk the clamp arm and screw a bit since it only needs to fit a car window. This makes it sturdier and more compact.
