The prompt
Create a production-ready parametric CAD model of a premium flower planter designed as a master model for making a silicone mold for concrete casting. This is NOT a decorative mesh. Create a real engineering CAD model with exact dimensions. Dimensions: - Height: 180 mm - Top outer diameter: 160 mm - Bottom outer diameter: 120 mm - Wall thickness: 10 mm - Bottom thickness: 12 mm - Drain hole: 20 mm Requirements: - Perfectly smooth cylindrical interior. - Flat bottom. - Flat top rim. - Exterior must look like a real natural stone carved from a large rock. - Random rock geometry. - Large irregular stone facets. - Small natural chips. - Soft weathered edges. - Natural cracks with shallow depth. - No repeating patterns. - Premium Scandinavian minimalist style. - High-end concrete planter appearance. - Suitable for luxury home decor. Manufacturing requirements: - 3° draft angle on outer walls. - No undercuts. - Watertight solid. - Manifold geometry. - No self intersections. - FDM printable. - Minimum feature thickness 3 mm. - Optimized for PLA printing on an Elegoo Centauri printer. After creating the planter, also create a complete silicone mold system consisting of: 1. Master Planter 2. Inner Core 3. Two-piece rigid support shell 4. Alignment pins 5. Bolt holes for M4 screws 6. Silicone thickness between master and shell: 10 mm 7. Vent channels 8. Pouring gate Export all parts separately as: Master_Planter.stl Inner_Core.stl Shell_Left.stl Shell_Right.stl Alignment_Pins.stl All parts must fit inside the build volume of an Elegoo Centauri printer. The STL files must be ready for slicing without any further editing.
