Grayscale 3D wireframe technical model render of a single vertical cylindrical industrial gas cylinder with an upper domed shoulder and a flat base, segmented by ring-like seams; a short neck with a side cylindrical knob valve connects to an upward metal pipe that bends near the top and ends in a long straight nozzle. The whole object is covered with light gray grid lines, no texture maps, on a pure white to light gray background, centered, frontal orthographic view, very narrow vertical aspect ratio about 1:8, even soft lighting, monochrome low-saturation industrial prop display style.
