These are 3d printable files for a Darksaber from Star Wars Rebels. It's idealized and you can install a soundboard and Neopixels. I do not recommend using a high power led as this is all plastic. No dueling either since... you guessed it... its plastic. I made holes ass seen on the pictures so you can hold everything with screws.
I will also provide a DXF or PDF of the blade if you want to cut it in poly-carbonate Plexiglas or acrylic. Please contact me if you need this file too.
