Here is on request my lightsaber that I made with light and sound effects based on the original adafruit project. not being perfect, I leave with the Fusion 360 creation files which will allow the best of you to modify it, to improve it.
I also changed part of the saber's operating code because on the original one, the effect of the LEDs didn't quite suit me.
You can find all the instructions on installing the card in the complete article which goes with the YouTube video made for the occasion.

I advise you to print the parts in PETG for more resistance.
