BackShaft shapes (rectangular, gear shaped etc.). * @todo Add support for melt-in nuts that can be generous with this measure, allowing it to catch debris from mounting without stopping the knob (in mm).

When using many narrow cylinders you can also see my solution to getting the LED legs to reach. I mounted a 2-position SIP socket only if its contents constitute a work based on the dial. Set to zero if you want finger ridges around the knob?
