Cutting inside walls for acrylic to slide into pew pew

Inner walls fit perfectly and are the exact right width to hold 1/8” acrylic panel. On to the electronics!!

Breadboarding mostly done! LEDs lighting up and have a button to cycle through 7 colors.

Retiring for tonight, hope to finish tomorrow!
