Printrbot LC Z Stop Dial

thingiverse

This dial simplifies z-stop adjustments on your Printrbot without the need for a screwdriver and aids in tracking changes. Choose from various premade STLs or use the customizer to create your preferred knob style, with 65mm being ideal for a stock Printrbot and 80mm for one with Brook's three-point bed leveler. Print using normal 40% infill, as cooling may be required for the long shaft. During printing, cut a 2-inch 6-32 screw to fit the knob's hollow end. Depending on print quality, you might need to drill or glue the screw in place. Replace the existing z stop screw with your new one, mark its top for easy tracking, and each revolution adjusts the z axis by approximately 0.79 mm. A second version with a thicker knurled knob is available, while a dial with a pointer was added based on Michele31415's suggestion.
