The prompt

Keep all 5 existing fuselage frames unchanged. Add exactly 8 straight longitudinal stringers connecting F1 to F5. Stringers are 2.5 mm square. Place them symmetrically: 2 along the lower corners, 2 halfway up the side walls, 2 at the upper shoulder corners, 2 along the upper fuselage. Each stringer must touch and join every frame. Do not add spars, braces, skin or other geometry. Do not change the frame shapes.
