The prompt
Create a simple, functional 3D-printable basic wafer support holder for a 4-inch (approximately 100 mm diameter) silicon wafer. Design dimensions: - Square base plate: 140 × 140 × 5 mm - Centered circular raised platform: 110 mm diameter × 5 mm height - Total height: 10 mm - Base plate corner radius: R2 mm - All dimensions in millimeters. Design requirements: - Flat square base with a centered circular raised support. - Completely flat top surface for supporting the wafer. - Base and circular platform must be one connected solid body. - Suitable for FDM 3D printing. - No hollow cavities, fragile features, or unsupported overhangs. - Keep the bottom surface flat and stable. - Add only 0.5 mm chamfers to sharp outer edges. Do NOT add vacuum holes, clamps, screws, springs, rotation mechanisms, side walls, positioning pins, or wafer-centering features. This is Type A, a basic support-only design. It will later be compared with Type B, which has three-point wafer positioning features. Keep the geometry simple and practical. Generate a parametric CAD model with isometric, top, and side views. Export as STEP and STL files.
