Wanhao Duplicator 4S Z-stop height mod

thingiverse

a simple design to activate your z-height stop at a lower bed height, to allow easy fitment of a glass bed. simply scale the z height in your slicer to your requirements and place the spacer around the bottom of your z screw pillar. the thing is 3mm deep, so will stop your z-home at 3mm lower than normal, use this with 3mm glass bed added. if you need to scale for thicker glass just use your slicer scale settings.
