The prompt
Create a parametric 3D model of the VIPER tail-sitter VTOL interceptor drone. Make a central hollow cylinder with outer diameter 138 mm, wall thickness 1.0 mm, and length 325 mm[cite: 1, 6]. Add a parabolic nose radome at the top with length 110 mm, tapering from 138 mm down to a rounded apex, bringing total length to 435 mm[cite: 1, 6]. At mid-body (Z = 180 mm), add four symmetric horizontal composite motor arms in a 90-degree cross pattern with a tip-to-tip span of 260 mm[cite: 1, 6]. At the end of each arm, place a vertical cylindrical motor pod with 35 mm diameter and 45 mm height[cite: 1]. At the base of the cylinder (Z = 0), attach four swept landing fins aligned with the arms, flaring out to a 210 mm diagonal stance[cite: 1, 2]. Output in millimeters.
