Alps Rotary switch knob (Used in 6pos mode switch mod on Turnigy 9x)

After modding the Turnigy 9x with the 6pos mode switch,
I was tired of having to mount gigantig potentiometer switches to my Alps rotary switch.
This is the smallest knob that makes sense. It has a tiny indicator pocket at the top, that can easily be filled with white paint, so you always know the position of the switch.
THe Alps rotary switch has a 6.1mm diameter, so this should be a tight fit, depending on how well your printer behaves on hole diameters ;)
The length of the Alps switch has to be cut to a max of 11mm.
