The prompt
Create a 3D-printable CAD model of a solid star-shaped block. Requirements: Shape: 5-point star block, flat top and bottom. Total block height: 27 mm. The block must contain 50 vertical blind holes. Hole diameter: 10 mm. Hole depth: 20 mm. Holes start from the top face and do not go through the bottom. Minimum distance between holes: 10 mm wall-to-wall clearance. Minimum distance from any hole to the outer edge of the star: 10 mm wall-to-wall clearance. Therefore, hole center-to-center spacing must be at least 20 mm. Hole center must be at least 15 mm from the outer edge: 5 mm hole radius + 10 mm clearance. Arrange the 50 holes in a clean, evenly distributed pattern that follows the star shape. Increase the overall star size as needed to fit all 50 holes while respecting spacing. Add small edge fillets, around 1–2 mm, to make the part easier and safer to handle. Keep the bottom surface flat for 3D printing. Export as STL and STEP files. Units: millimeters. Design intent: The part should look like a large solid star-shaped organizer or holder, with 50 clean cylindrical holes on the top surface.
Parameters
| Name | Value | Range |
|---|---|---|
| Star Outer Radius | 200 mm | 120 – 350 |
| Star Inner Radius | 80 mm | 40 – 160 |
| Block Height | 27 mm | 15 – 80 |
| Hole Diameter | 10 mm | 5 – 20 |
| Hole Depth | 20 mm | 5 – 60 |
| Hole Center-to-Center Spacing | 22 mm | 20 – 50 |
| Hole Center to Edge Clearance | 15 mm | 10 – 30 |
| Edge Fillet Radius | 1.5 mm | 0.5 – 3 |
Every value above is a live dimension. Open a model like this in the editor and each one becomes a slider you can drag before exporting.
