As-yet untested; the power distribution unit for the photomultiplier tubes on our 6000 series detector has potentiometers with 0.125" diameter, smooth, round shafts. They are long shafts, perhaps 1.75" to 2", so I used the customizer option to extend the shaft hole through the top of the knob.

This version (v1) has 3.175 mm (0.125") diameter shaft hole. It may be friction fit to the shaft, or may require the use of a 3mm set screw. If a set screw is used, it may be useful to grind a slight flat onto the shaft.
