Knobs for Pocket Operator

Hi
The potentiometer knobs of the pocket operator are also rather small and difficult to operate, especially if you have thick fingers - like me. ;-)
Since I already made knobs for my KORG monoton Delay, I also made some for my Pocket Operators.
I also tried different designs for the position indicator on these knobs. First without, then with a simple stroke etc., then I thought about using the two small symbols from Teenage Engineering and made different designs with them. Since I still haven't equipped my 3D-Printer with a smaller than 0.4 mm nozzle, a filigree design was again not good to print. So I decided to make the symbols relatively large.
The symbols are embedded deeper and can be filled with a contrasting color or with a color matching the color concept of the respective Pocket Operator. Or the knobs can simply remain as they come out of the printer.
