Wanhao Duplicator i3 LCD Control Knob

thingiverse

I was never a fan of the standard knobs that came with my Wanhao Di3 because their sides were just too smooth and lacked any real grip. I decided to create something better. The stock knob can be removed with nothing more than bare hands, and installing the new one is not overly complicated. This upgraded knob features 10 teeth, so two steps equal a single tooth of rotation. For ultimate convenience, it's recommended that you install it with one tooth pointing straight up. If you find that it turns out to be either too tight or loose, this design is easily adjustable.
