With the PCBs in hand revisions have been made after much collaboration and iterations.

-Standoffs to make sure any pins don't touch the plastic for static concerns.

-"Click-in" corner reliefs to hold the board precisely in place.

-Opened up the SAO connector hole so full contact can be made. (due to the standoffs)

-2 layers of plastic in front of the LED so it can shine through.

-Protrusions in the "bow-ties" and slots in the body for  a "click-in" fit.

-Clips to hold the bodies together for wearable or larger portable displays.

I think we have a "final" version ready for mass production.
