About this 3D model

Due to lack of a gun i'd like to have fot one of my RPG figures, i designed this gun with the Blueprints the Rulebook gave me. If you're looking for this exact gun, have fun. I measured it based on pictures of the S-5 heavy blaster in relation to the drawing of this gun. Found an auction of one of the original props with exact measurements, scaled both picteres at the same time to the right scale and scaled the model afterwards to the more or less correct size. Scale 1:1
