Simple Z axis adjustment helper - RepRapPro

This little extension saves me a lot of time and don’t need a hex key. I could have printed a knob but already had one handy. Note that the m nut is on the lower side like the original adjustment. Put the screw head on the bottom so most any knob can be used. The Spring, washers and nut are from the original adjustment and a longer 35mm M3 screw
