打开的打火机3D线框素模

生成一个打开状态的翻盖金属打火机3D线框素模，整体浅灰单色，不表现真实材质颜色。机身呈竖向长方形，左上方翻盖以铰链为轴掀起，盖面平坦，边缘圆滑；顶部露出带多个圆孔的方形防风罩、右侧打火轮、左侧凸轮压杆及铰链结构。机身正面和侧面布满三角网格与不规则几何嵌板线框，类似地形分块面板，线条细密，表面带轻微明暗层次和边缘高光。背景为纯净浅灰，无地面投影，主体占满画面，机身位于右侧，翻盖向左上方展开；3/4视角近景，柔和的棚拍漫射光，低对比灰调，画幅约4:3，突出工业设计结构细节与线框拓扑，不出现文字。

Render a 3D wireframe clay model of an open flip-top lighter, monochrome light gray, without realistic material colors. The rectangular body stands vertically; the lid is hinged at the upper left and tilted open toward the upper left, with a flat top and rounded edges. The top exposes a square perforated wind guard with multiple circular holes, a flint wheel on the right, a cam lever on the left, and hinge details. The front and side panels are covered with triangular mesh and irregular geometric panel wireframes, like a topographic segmented pattern, drawn with thin lines and subtle shading and edge highlights. Clean light gray background, no ground shadow, the subject fills the frame with the body on the right and the lid spreading to the upper left, three-quarter close-up view, soft studio diffuse lighting, low-contrast gray tones, approximately 4:3 aspect ratio, emphasizing industrial design structure and wireframe topology, no text.
