The prompt
# Stage 1 – Pelton Wheel Base Only Use the attached reference image as the exact visual and structural design reference. I want you to recreate the circular flat wheel base shown in the reference image. IMPORTANT: Do not redesign it into a thick solid industrial disc or a conventional turbine wheel. ## Main Geometry - A thin, flat, circular disc. - Smooth, planar front and rear surfaces. - Circular outer perimeter. - No integrated buckets, blades, paddles, or cups. - No unnecessary spokes or decorative ribs. - The design should visually resemble the transparent circular plate shown in the reference image. ## Bucket Mounting Holes - The wheel will eventually carry 14 separate Pelton double-cup buckets. - Create 14 equally spaced mounting stations around the outer circumference. - Each station must contain exactly two adjacent screw holes. - Total: 28 mounting holes. - Angular spacing between stations: 25.714 degrees. - The two holes at each station must match a future removable bucket mounting base. ## Dimensions - Maximum assembled runner outside diameter, including the buckets: 150 mm. - The bare disc must be smaller than 150 mm. - Propose a suitable disc diameter and thickness. - Keep the hole diameters, spacing, central mounting interface, and disc thickness editable. - Do not invent final dimensions without showing them for approval. ## Manufacturing - The entire disc must be 3D printable. - Use a flat FDM-printable geometry. - Consider PETG or PLA+. - Ensure adequate material around the mounting holes. ## Deliverables Show: 1. Front view matching the reference. 2. Side view showing the thin disc profile. 3. Isometric view. 4. Dimensioned engineering drawing. 5. Editable parametric CAD model. 6. STEP and STL exports. Do not create any buckets at this stage. Do not create the complete turbine. Only model the circular wheel base shown in the reference image.
