Opel Kadett Rallye Badge / Emblem | Classic Rallye Script with Checkered Flag | Vintage Opel Replacement | 3D Printable STL

3D printable reproduction-style Opel Kadett Rallye badge / emblem, recreated from an old photograph of the original rare badge.

This Kadett Rallye emblem was modeled because the original badge is rare and difficult to find. The design was carefully traced from a photograph of an original badge to recreate its characteristic vintage appearance.

The model features the distinctive “Kadett” script, “RALLYE” lettering, and checkered flag pattern at the end, all integrated into the long rectangular badge.

This is particularly useful for classic Opel restoration projects, replacement of a missing emblem, display purposes, or reproduction of a badge that is increasingly difficult to source in usable condition.

Design Details

The badge includes:

Raised Kadett script
Raised RALLYE lettering
Checkered racing-flag detail
Long rectangular backing plate
Vintage Opel Rallye-inspired proportions
Separate raised areas suitable for multi-color printing or painting

The design was traced from an old photograph, rather than modeled from verified factory CAD data. Minor dimensional or typography differences from an original period badge may therefore exist.

Vehicle Compatibility

Intended for:

Opel Kadett
Opel Kadett Rallye
Classic Opel restoration projects
Vehicles originally equipped with a matching Kadett Rallye badge

Because the exact original Opel part number, model year, mounting position, and dimensions were not provided, I would not add an unverified OEM number or claim a specific Kadett generation.

Compare the STL dimensions and mounting method with your original badge or vehicle before printing.

🖨️ Printing Recommendations

For exterior automotive use:

Recommended material: ASA
Good alternative: ABS
Alternative: PETG
PLA not recommended for permanent exterior installation
Layer height: 0.08–0.12 mm
Infill: 50–100%
Perimeters: 4–5
Print visible face upward for clean raised lettering

Because the badge contains fine script and checkered details, a 0.25–0.4 mm nozzle and fine layer height will provide better definition.

For multi-color printers, the raised lettering and checkered sections can be assigned different filament colors. Alternatively, print the complete badge in one material and paint the raised details afterward.

🎨 Finishing

For a more period-correct appearance:

Sand the backing surface where necessary.
Apply plastic primer.
Paint the main badge surface.
Carefully paint the raised Kadett and RALLYE details.
Paint the checkered section separately.
Apply a suitable protective clear coat if desired.

For exterior installation, use an automotive-grade emblem adhesive / double-sided trim tape suitable for the vehicle surface.

⚠️ Reproduction Note

This model is a recreated replacement based on an old photograph and should not be represented as a genuine NOS Opel factory badge.

It is intended as a practical reproduction for restoration when an original badge is unavailable or prohibitively difficult to obtain.
