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.
