yellow knob 3d model

A single, isolated industrial mechanical 3D model of a complex mechanical tool assembly, derived from image_11.png. The top component is a perfectly smooth, polished, flat, cloud-shaped (lobed) knob made of vibrant yellow polymer, with precise black outlines. It is seamlessly integrated onto the main body. The main body is a continuous, vertical, thick-walled cylindrical shaft of substantial height (around 10cm scale equivalent), finished in brushed green metal. Crucially, the external surface of this green shaft features a meticulously detailed, deep, precise, continuous mechanical screw thread (internal threading pattern) that runs perfectly straight, without interruption, from the very top end where it meets the knob all the way down to the bottom end, exhibiting a gradual, smooth vertical advance. The height-to-diameter ratio emphasizes its elongated form. Studio lighting, isolated on a seamless white background, orthogonal schematic view (combination side-view and three-quarter pe
