aerosol actuator 3d model

High-resolution engineering CAD 3D model of a complex aerosol spray actuator mechanism for a 65mm can. The device must feature a precise cylindrical clamp tightly gripping the top rim of the metallic can, secured by visible bolt heads. Rigidly attached to the clamp is a smooth vertical linear guide housing a precise, moving rack gear with clearly defined teeth. A standard MG996R servo motor is mounted on the side bracket; its pinion gear meshes accurately with the rack. From the top of the sliding rack, a smooth, curved S-shaped offset arm extends inward over the can's nozzle, ending in a precise horizontal pressing head. Materials are industrial matte grey PETG plastic and silver metal. Professional mechanical product look, clean geometry, realistic tolerances. Focus on the rack-and-pinion assembly.
