About this 3D model

What I would reccomend for you is to scale it up to the size you would like, the size it is at now i think is too small but you can figit around with it until you are satisfied. But what i would reccomend is on the z axis is 5.3789 mm, y axis 38.2502 mm, x axis 38.2502 mm, and with all of those measurements you will get the sword similar like to the photos. :)
