This is a replacement part for the Fiat Palio brake light, developed through reverse engineering of the original component.
The original part of the brake light assembly often breaks or degrades over time due to heat, vibration, and prolonged sun exposure. This model was recreated to allow easy replacement using a 3D printer, avoiding the need to replace the entire brake light assembly.
Reverse Engineering Process
The geometry of this part was reconstructed using photogrammetry. The original component was scanned and processed using COLMAP to generate a 3D reconstruction. This scan was then imported into Blender, where the final CAD model was created using the reconstructed mesh as a reference.
This approach allowed accurate capture of the original geometry while still enabling improvements to the design.
Structural Improvements
Some modifications were intentionally introduced to improve durability compared to the original plastic part:
Increased wall thickness in critical areas
Additional structural ribs added to reinforce the plastic body
Geometry adjustments to reduce weak points present in the original component
These changes aim to make the printed part more resistant to cracking and fatigue while maintaining compatibility with the original mounting points.
Printing Recommendations
Due to the external curved and angled geometry of the part, using supports is recommended to ensure good surface quality and dimensional accuracy.
Recommended settings:
Supports: Recommended (especially for the outer curved surfaces)
Layer height: 0.2 mm
Infill: 30–40%
Walls: 3–4 perimeters
Materials
The prototype part was printed using Tritan, which provides good impact resistance and durability.
However, the following materials are recommended for most users due to their availability and suitability for automotive environments:
ABS – good heat resistance and mechanical strength
PETG – easier to print and still provides good durability
For outdoor use, materials with better heat and UV resistance are preferred.
