Wanhao-Di3-Jog-dial-knob

thingiverse

This dial serves as an upgraded replacement for the Wanhao Duplicator i3 dial, equipped with a jog dial featuring a precision-cut finger indentation designed to simplify navigation through the device's menu system. A 6.5mm diameter hole has been printed using high-quality PLA, resulting in a snug friction fit that may require slight modifications - sanding or scraping the lip of the hole will help it slide smoothly into place within the encoder located just in front of the screen.
