Had another go at a pop-through button design.
So you print it flat, and upside down, then flip it over and pop it through so it stands up.
This gives a nice finish on both the button and the lip, and makes it one piece.
Or so goes the theory.
Changed it to an all-flexible, 3 part design with no supports required for printing.
Moved the Dotstar modules to the ends. I have an idea for diffusing the light. We'll see if it pops correctly first. The last one I tried I believe the corner radius was too small so it didn't work right.
