A mixture knob and button for a Cessna 172 flight simulator panel. I purchased a genuine Vernier mixture control for my simulator project but I modeled this to the calipered dimensions of the real mixture control (Aircraft Spruce A-790) for others to use.
The preview .stl file is provided only for a preview of the knob and button as they would be aligned when assembled. The button travel in the real mixture control is about 3mm.
