Clamp With Articulated Arm Connector

I liked both of the designs and needed a way to clamp the arm to my shelf near the printer. So this is just the quick and dirty way scaled down and merged using the Windows 3D-Builder. Works great! For me the original screw didn't work at a 50% scale. It slipped through the thread, so I tried a scale of 53% which does the job, but it might be a little too tight. So I also uploaded a 52% scaled version.
