Parametric Camp Gas Stove Knob with Grip (or volume control, or

Summary No need for the pliers to operate your broken gas stove, next time you go camping. I have also used this thing for a volume control knob. Instructions Set the parameters within openscad. Print away. If required to secure knob onto shaft place an m3 nut in the nut trap and slide the holding m3 bolt through hole and tighten. Point to remember when setting variables- flat parameter refers to flat to slide onto the shaft and is expressed as a percentage of diameter of the shaft (i.e. .5 would be half) or set to 0 if not required.
