Replacement Knobs for HP/Agilent/Keysight Equipment

These are a set of replacement knobs commonly used across much of the equipment produced by HP/Agilent/Keysight.  Since replacement knobs direct from Keysight or Ebay are way too expensive I decided to design a set of knobs in the common sizes.  These should be compatible with most, if not all, Keysight/HP/Agilent equipment which has potentiometers or encoders with a D-shaft.

If the fit on the D-shaft is too loose or tight, you might need to slightly tweak the horizontal expansion settings to adjust the fit.
