Years ago, I made a Sword of Dios resin-casted kit that was pretty popular. I feel like I sent out 1-2 of those swords a week. Even sent them off to Australia and Germany.
I sculpted this in Zbrush, measuring as I went along, to try and match the dimensions as much as possible.
3D files include the 3 pieces that make up the sword handle and then 5 pieces for the blade. It's HIGHLY recommended to use a 5mm rod to help strengthen the print and aid with alignment, as I did hollow the blade to incorporate one.
