"Create a high-accuracy 3D model of the stun gun shell (Type 704/928/958).Model only the external plastic housing with realistic proportions and smooth edges.Dimensions: length 120 mm, width 40 mm, thickness 30 mm.Include ergonomic finger grooves on the grip (3 grooves), a side switch on the right, a front dual-electrode area, and a bottom charging port placeholder.The internal cavity should be hollow for future electronics, with 2–4 mounting pillars for screws.Deliver the model as STL and split into two symmetrical halves (left and right shell).The shape must be identical to the reference image."
