Cut each layer (along with the "Edge") layer from acrylic. Cut the segments from clear or red acrylic and clue into place on the "mid" layer. Place 118 LEDs in the "jig" layer and solder the positives together to make a common anode display.
The five layer stack assembles with M5x25 bolts and can be hung from the two slots.
Software coming soon.
