A straightforward replacement dial for the Prusa I3 MK2 is provided. It closely resembles the original, but features a flat top surface, lacks chamfering on the sides, and includes a small recess at the end of its arm for either coloring with a marker or utilizing a pen tip to accelerate spinning. Updated May 10, 2018: The depth of the recess on the dial's arm has been increased from 0.5mm to 3mm, significantly enhancing performance when using pen tips.
