This is a sentinel sword out of the game DOOM Eternal. This particular sword can be found on the level Sentinel Prime, about half way through. I made this cause it looks cool and that no one else has done something like this. Also the original size for this sword is 1300mm so you might need to scale to fit your requirements.

3D PRINTING SETTINGSId recommend starting with a high infill, about 40% for the handle and drop it off closer to the tip, to allow for better weight distribution, I'd say about a 5-10% infill.
