The prompt
# CAD DESIGN – CIRCULAR LID FOR A 600 ML LABORATORY BEAKER Design ONLY a circular lid for a 600 mL laboratory glass beaker, intended for FDM 3D printing. Do not design the beaker, electrodes, cables, connectors, terminals, holders, or any additional structures. ## 1. Main geometry - Circular flat lid. - Outer diameter: 110 mm. - Thickness: 4 mm. - Smooth, flat upper surface. - Slightly rounded external edges. ## 2. Lower fitting rim The lid must have an integrated circular lip underneath, allowing it to fit inside the beaker opening. - Outer diameter of lower lip: 99 mm. - Height: 4 mm. - Wall thickness: approximately 3 mm. - Concentric with the main lid. - Designed for a beaker with an estimated internal diameter of 100 mm. - Allow approximately 0.5 mm radial clearance. ## 3. Electrode openings Create exactly TWO circular through-holes in the lid. - Hole diameter: 8.4 mm. - Both holes must pass completely through the 4 mm thick lid. - Position them symmetrically around the geometric center. Coordinates relative to the lid center: - Hole 1: X = -5 mm, Y = 0 mm. - Hole 2: X = +5 mm, Y = 0 mm. Distance between hole centers: 10 mm. The geometric center itself must remain completely solid and untouched. ## 4. Manufacturing requirements - Units: millimeters. - Single integrated solid part. - No additional components. - No raised structures. - No threads. - No electrical connectors. - No cable channels. - No electrode models. - Watertight and manifold geometry. - Suitable for FDM 3D printing. - Recommended material: PETG. ## 5. Deliverables Generate: - One complete editable parametric CAD model. - STL file ready for 3D printing. - STEP file if supported. - Top, bottom, side and isometric views. IMPORTANT: The final object must consist exclusively of a flat circular lid with a lower fitting rim and exactly two electrode holes. Do not add any other structures or components.
