audi rs6 avant 3d model

Create a 3D-printable model of an Audi RS6 Avant with ABT tuning kit. The model should be optimized for 3D printing with a solid, watertight mesh (no holes), proper wall thickness, and clean geometry. Include ABT-style body modifications such as aggressive front bumper, rear diffuser, side skirts, larger wheels, and sporty details. Keep the design recognizable but slightly simplified for print stability. Avoid extremely thin parts; ensure all elements (mirrors, spoiler, rims) are thickened for durability. Model should be manifold, single-piece if possible, and scaled proportionally. Style: realistic but slightly simplified, clean topology, high detail suitable for FDM 3D printing.
