Audi S1 Hoonitron Functional Key Holder - Gymkhana Tribute
Design Concept
Inspired by the cutting-edge Audi S1 Hoonitron, this wall-mounted key holder is a tribute to the legacy of Ken Block and the future of electric performance. Meticulously modeled in Fusion 360, this piece captures the aggressive aero-package, the iconic front grille, and the futuristic headlights of the e-tron rally beast, ensuring a high-fidelity look that is perfectly optimized for FDM 3D printing.

Key Features
Precision Fusion 360 Engineering: Every line and curve has been refined to ensure a professional finish and clean printing geometry.
Integrated Keyslot Mount: The back features a built-in keyslot (keyhole) mechanical mount. This allows the holder to slide securely over a wall screw for a flush, invisible, and strong installation—no messy adhesives needed.
Reinforced Dual Hooks: The hooks are integrated into the front splitter design, engineered to carry the weight of multiple heavy keyrings comfortably.
Printing & Material Advice
Recommended Material: PETG. To ensure the structural integrity of the integrated hooks and the mounting slot, PETG is strongly recommended. It provides the necessary impact resistance and thermal stability for a long-lasting functional household accessory.
Layer Height: 0.16mm - 0.2mm for an optimal balance between surface smoothness and print time.
Infill: 20% (Gyroid recommended) for solid internal support of the mounting area.
Supports: Light supports are recommended for the front aero-splitter and the internal cavity of the keyslot.
Assembly Instructions
Print: Use PETG for maximum durability of the mechanical mounting system.
Wall Setup: Install a screw into your wall, leaving the head protruding about 3-5mm.
Mount: Align the integrated keyslot on the back of the Hoonitron with the screw and slide it downward until it locks into place.
