Release Version 2.1

Version 2 solved most of the smoothness problems reported in version 1. But the twist axis was still problematic. With light springs and light workpieces, twist axis drag was minimal. Unfortunately, with heavier workpieces and heavier springs, it became noticeable

Version 2.1 introduced a stronger twist axis axle and hinged magnet. This solved the dragging problem
