Mercedes M-Class ML W163 Facelift Front Bumper Grille – A1638851581 / 1638851581

In the late 1990s, Mercedes-Benz entered the SUV market with the M-Class W163, a vehicle combining versatility, comfort, and off-road capability. Its updated version from the early 2000s, known as Phase 2 or the facelift model, introduced a modernized appearance while retaining the model's robust and elegant identity. Among its distinctive bodywork features, the front bumper ventilation grille contributes to the vehicle's harmonious appearance and allows air to flow through its lower front section.

Exposed to weather conditions, road debris, and minor impacts, this trim component can gradually crack, deform, or deteriorate. To support enthusiasts in their restoration projects, Shapline offers a digital reproduction of the ventilation grille corresponding to Mercedes-Benz part number A1638851581.

Divided into four sections to make 3D printing easier, this design includes three assembly methods to choose from: sliding rails, connecting spacers, and thermoplastic rivets, allowing you to adapt the manufacturing process to your equipment and preferences.

• Sliding rail assembly: this first version uses sliding rails positioned on each side of the components, ensuring simple and precise assembly.
• Spacer assembly: this second version uses connecting spacers inserted into the printed components, providing a secure and accurately aligned assembly.
• Rivet assembly: this final version features protruding pins on each component, which can be progressively melted using a soldering iron to form strong and durable rivets.

Product contents

The package includes:

• All 3D printing files (STL) for the classic ventilation grille A1638851581 / 1638851581 for Mercedes-Benz ML-Class (W163), including all 3 assembly methods
• License of use

Important: Please note that this offer includes digital products only. The components and photographs shown are provided for illustrative and informational purposes only. We recommend using a 3D printer with a build plate measuring at least 25 x 25 cm (diagonal printing is recommended) to print certain parts. Otherwise, these parts may need to be divided into two sections.

3D printing recommendations

We recommend using ABS filament, which is better suited for automotive applications thanks to its strength, durability, and resistance to moisture and sunlight.

Assembly recommendations

Important: To ensure a strong and durable assembly when using the spacer or sliding rail mounting systems, you can apply an adhesive compatible with the filament or material used for 3D printing to permanently secure the components together.

For the rivet mounting system, we recommend using a soldering iron to gradually melt the protruding pin and form a rivet that holds the components together. Always follow the necessary safety instructions when using your equipment and wear appropriate protective equipment during this operation.
