The default knob can only be turned by pushing a finger slightly against it - but push too hard and you click by accident. This new knob is much less annoying to use - I promise.The knob is easy to make - no support or finishing work required. To remove the original knob, I glued something to it and then pulled it straight out (but don't blame me if something breaks).Settings:- shell thickness 0.8 mm (using a nozzle of 0.4 mm), that way the part will be built mostly of "shell" and very little infill- 0.8 mm bottom / top thickness- layer height 0.1 mm- no support
