micrometer screw gauge 3d model

A technical, clear exploded view 3D illustration of a metric micrometer screw gauge, showing its internal components. All parts are separated along a central axis: the U-frame, the fixed anvil, the movable spindle, the main scale barrel (sleeve) with 0.5mm graduations, the rotating thimble with 50 divisions, the internal precision ground screw thread, the ratchet stop assembly, and the thimble cap. Materials differentiate steel (silver) from cast iron (black). Each major part is subtly labeled with clean English text (e.g., "Frame", "Spindle", "Thimble Scale"). Bright, even lighting, clean engineering diagram style on a light gray background.
