I have a mouser cart saved, so that should make it easier for people.
…but unfortunately the 15mm shaft encoders (in either flatted or knurled) are out of stock right now at both Mouser and Digikey. The 20mm shaft ones are available in either place. Switch caps are also in low supply.
I’m hoping this does not turn into another “Great 16n Fader Shortage of 2019” situation.
