A sword with a wonderful design, suitable for both this character from the game and for the original vampire cosplay. I made this sword with a light, so the guard has an inner channel for wiring and a slot for a battery and a button Sword length 1 m, weight of printed parts about 420 g at 15% filling The sword is divided into 8 parts for printing on a 3D printer of a standard size (the largest part is 209 mm high). The file archive contains screenshots and descriptions with additional information about printing.
You need 12 mm diameter and less than meter long rod or tube for core and 8 small (about 20 mm) pieces of wood stick (like sushi sticks) for assembling.
3D models of accessories are designed for printing on a photopolymer printer, but they can also be printed on a regular FDM printer with more accurate settings.
These details was created with an approximate size, you need to calculate the size that fits the proportions of your suit and increase or decrease these details and gems to them by the appropriate percentage of the scale.
I used transparent tinted photopolymer resin for all the gems. But you can also print them on a FDM printer, make a silicone mold and cast from epoxy resin.
