Experimented with making 3D printable buttons.

Tried making a planer design where it could be printed flat, then the buttons popped through to become raised. Might have worked, but then it got a bit more complicated when I decided I wanted some blinken-lights.

I've settled on a layered approach so everything can be printed in the best material for the job, and without overhangs/supports.

TPU cover, clear PLA light pipe, TPU contact pad, and ABS retainer ring.
