✂️ Customization Guide
Adjust these parameters in the OpenSCAD Customizer to make it yours:

| ring_width | Width/height of the ring band (mm) | 10 | 5–20 |

🖨️ Printing Recommendations
| Setting | Recommendation |
|---|---|
| Material | PETG or PLA+ (PETG preferred for durability and flexibility) |
| Layer Height | 0.12–0.16mm (finer layers = sharper blade tips) |
| Infill | 80–100% (ring needs to be solid for strength) |
| Supports | Not required |
| Orientation | Print upright (ring standing on its edge) for best blade quality |
| Post-Processing | Lightly sand the blade tips for extra sharpness |
⚠️ Safety Note: The printed blades can be sharp enough to cut skin. Handle with care!
💡 Tips
- Measure your finger diameter with calipers for the best fit
- Start with a lower blade_protrusion (1–2mm) and increase if needed
- More blades = smoother cut; fewer blades = more aggressive tear
- Thinner blade_thickness (0.5–0.8mm) gives sharper edges but is more fragile
- Follow for more parametric models!
- Give it a like and share if you liked the model!
