Sombra, the recently added character to overwatch uses this gun in the battles. this model are molded from the ground up and not riped from the game. i replicated the real model from billard using screenshots from the animated short.
if you want to print this full size just scale the individual pieces up by 1000%.
otherwise if you want a smaller version, i divided it up in to three pieces (Sombra full full top, buttom and top end)
the pictures are of the small version, scaled up by about 240%

feel free to write to me if you have any question of how to print this out :D
