This 3D model is a keychain inspired by the Audi 4.2 FSI V8 engine gasket design. Faithfully modeled to capture the authentic geometry, including water and oil passages, it is offered in two versions:

-V1: maintains the original gasket silhouette without additional features.

-V2: reinforced hole (5 mm inner diameter, 9 mm outer diameter) added for keyring attachment, ensuring durability in daily use.

Important:
Because the Audi 4.2 FSI is a V8 engine, each file includes two mirrored keychains:

One imitating the gasket of the left bank cylinders

One imitating the gasket of the right bank cylinders

Specifications:

Dimensions (each keychain): approx. 57.6 mm length × 29 mm width

Dimensions (file including both banks): approx. 57.6 mm length × 59.81 mm width

Thickness: 3 mm (optimized for daily use without bulk)

File formats: STL, OBJ, FBX, GLB, 3DS, BLEND, SVG (ready for 3D printing, rendering, and visualization)

Optimized design: lightweight, durable, and faithful to the Audi 4.2 FSI gasket geometry, including water and oil passages

This model is ideal for car enthusiasts, collectors, and anyone who appreciates the engineering heritage of Audi’s 4.2 FSI V8 engine, a hallmark of performance and precision.
