This is the main core for the KRCNC2 saber, which has been resized properly to be 1:1 with the real prop but with the benefit of accpeting electronics for light and sound. This was used for the phoenix prop V2 but tweaked for printing purposes. The holes are tapped (some 8-32 and some are 6-32) in the print but are not very strong threads so be careful.
This accepts a 1" main blade and 0.875" side blades. This is not meant dor dueling since its made out of plastic.
