## Validation

- 15 onset events transcribed.
- STL dimensions: 120 × 34 × 76 mm.
- STL: 972 facets, closed manifold, zero boundary edges.
- G-code generated with PrusaSlicer using a generic PLA FFF profile.
- Generic settings: 0.20 mm layers, 205 °C nozzle, 60 °C bed, 15% infill.

Important: the G-code is process-validated, not printer-specific. Select the actual printer, material, and safety profile before physical printing.
