Digitech 1101 Preamp Encoder Knob

Many years ago I bought a used Digitech 1101 preamp and some of the knobs were missing.  I did eventually get original Digitech knobs from the manufacturer, but that took a while.  In the mean time I designed all the knobs for the preamp, which mimiced their original design.

I once printed these knobs in TPU, but you could use a harder plastic if you like.  If I was to print these again I'd most likely use TPU and use a high infill so that it doesn't feel squeeshy.  I imagine that these would work for other electronics as well.
