Description
A larger adjustment knob for the Eureka Mignon Zero that is easier to read and far more precise and repeatable than the stock knob. Printable without AMS via manual filament changes.
This remixed version has wider tick marks and numbers for easier printing upside-down without the markings squeezing shut. Printed on a textured bed results in a high quality surface finish that isn't obviously a 3D print. The Mignon Zero has a larger 32mm diameter stock adjustment knob. The included STL will fit the Zero and any other grinder with a 32mm knob. I also modified the .scad file to expose the inner knob diameter and debossing/emobossing depth to the user for easier modification.
Printed with a 0.2mm nozzle at 0.12mm layer height with two swaps to white filament (for symmetry) on an Ender 3. Make sure to get the indicator arrow from the original model! I glued mine on with a dab of hot glue which can be easily peeled off in the future if needed.
