20 kg Rectangular Single-Point Load Cell

Create a realistic 3D CAD model of a rectangular aluminum single-point load cell (20 kg capacity). **Main body geometry:** - Model the sensor as a long, narrow, solid rectangular aluminum bar. - The body has a uniform rectangular cross-section with slightly chamfered edges. - Both ends are thicker, solid mounting sections. - The center section contains a distinctive large circular cutout passing vertically through the thickness of the bar, forming a narrowed, flexible strain-gauge beam structure. - The central cutout should have smooth cylindrical walls and rounded transitions. - The central sensing region should be narrower and structurally thinner than the two mounting ends. **Mounting holes:** - Add four threaded mounting holes, two on each end of the bar. - Arrange the holes symmetrically along the longitudinal axis. - Each end has two holes positioned along its top face. - Holes should be cylindrical with visible internal threading or simplified threaded bores. - Keep the mounting surfaces flat. **Electrical wires:** - Add four insulated electrical wires emerging from one short end of the sensor. - Use red, black, green, and white wire insulation. - Wires should be flexible, slightly curved, and loosely bundled together. - Expose a small amount of metallic conductor at each wire tip. **Additional details:** - Add a small rectangular label on the front-facing end of the sensor. - The label should display "20kg" with a downward-pointing arrow underneath. - Use a matte silver-white aluminum finish. - Maintain realistic mechanical proportions and smooth machined surfaces. **Modeling requirements:** - Create the object as a single mechanical sensor assembly. - Use accurate solid geometry rather than a flat representation. - Ensure all mounting holes and the central cutout are actual subtractive features. - Keep the electrical wires as separate solid bodies. - Use realistic fillets and chamfers. - No background, no mounting accessories, no additional components.
