Small Lightsaber

thingiverse

I designed small lightsaber for my children. It is really short, because blade fits to my 3D printer (175mm) and also, it is easier to controll for small children. Maybe it is more "dagger" than "saber" And yes, I know how it also looks, but dont try that, wall is not very thick :D Model is designed for one 18650 battery. I have used LiFe 3,6V, but you can use any of this size. You will only have to choose the right resistor value. There are wires soldered on battery cell (the one coming along the battery must be thin to fit in). Battery wires are fitted with JST plug (https://images-na.ssl-images-amazon.com/images/I/61QvVvy7sNL._SX355_.jpg) in the area of switch. Switch is very cheap one with aretation. Also LEDs are normal ones 5-10mm 8000mCd
