threaded cylinder 3d model

A single, isolated mechanical 3D model of a hollow industrial cylinder (tube) for a red industrial scissor jack frame, specifically designed as a functional, thread-compatible component for 3D printing. The main body is a robust cylindrical block with a textured, matte black industrial steel finish and micro-chamfered edges, based on image_0.png. Crucially, the entire length of the internal bore must feature a high-precision, deep-recessed, 60-degree V-profile internal mechanical screw thread (internal threading) that is meticulously designed to accept and perfectly engage with a standard matching thread profile, allowing a screw or the jack's main shaft to rotate freely and advance along the entire channel. This threading must run completely and unobstructed through the bore. All internal edges must be sharp and precise, ensuring mechanical functionality.
