Build a sci-fi inspired bike light using Adafruit Feather and NeoPixels.The headlight fixture was inspired by rocket boosters and jet engines. I had the idea of an illuminated edge band that wraps around a cylinder with an illuminated inner core. By combining black PLA and translucent PLA, you can mask out certain geometry while illuminating other elements. I've been meaning to design specifically for dual extrusion such as the Ultimaker 3 and this is what I came up with.
