I really liked the idea that Optagon thing:4556291 had with the interchangeable icons but wanted a lower profile case.
I redesigned it without the angle. It's made for an arduino nano, I just use double sided tape to hold it in place. The cable just goes in through the slot.
I've also recreated the icons to have a 0.6mm base to be printed in white and act as a light diffuser. You can just insert a pause in your print and do a filament change like I did. I just used a small blob of hot glue to hold the LEDs in place.
I modified the sample ino from the github page to control the LEDs. I've included my cpp code to flash to the arduino nano. It can be used with visual studio code or you can probably change it to an ino to use with the Arduino IDE.
I'm no programmer but if you look at the code, there's low_color and high_color arrays that just use RGB values. This allows you to set the color of the LED when the knob is at 0 vs the high_color which is the color when the knob is at 100% and it will transition between the colors as you move the knob. I'm sure there's simpler/cleaner ways of doing it but this works for me.
