Printrbot Simple Metal Color Change Clip

For owners of the Printrbot Simple Metal printer. Have you ever grown tired of pressing down against that very stiff spring while doing a color change? I actually find it painful, after about a second. Yes, the pressure can be relieved by working with the screw, but that takes longer. This small but useful part (navy blue, near center of picture) can be inserted around the screw to relieve the pressure and free both hands while you do a color change.
