(It's worth checking out because this was my first time doing anything related to micro controllers and LEDs. You'll be able to laugh at all my silly mistakes.)
I printed all the pieces with clear PLA. All the electronics are identical to the ones demonstrated in Adafruit's video. I used a combination of E6000 and hot glue to stick everything together. I did have an issue charging the battery though, I think I killed it so bad that the micro controller doesn't even recognize it. i just got a separate battery and a battery charger and that fixed the problem.
