This DarkSaber was based on the Star Wars Rebels TV show with a more realistic look. This is designed to be fitted with a soundboard, battery and neopixels. It is not meant for dueling, just to show off. This is just the emitter portion and you can get the rest of the parts from this list: https://www.shapeways.com/designer/gucabe/lists/darksaber
Tip: Print it in white and save a few bucks. Printing in color comes with a premium.
