1998 Chevrolet Silverado "OBS" Functional Key Holder - GMT400 Edition
Design Concept
Bring the definitive style of 90s American pickups to your wall with this highly detailed 1998 Chevrolet Silverado wall-mounted key holder. Meticulously modeled in Fusion 360, this piece honors the legendary OBS (Old Body Style) GMT400 truck generation. It accurately captures the iconic split-front grille with the central Bowtie emblem, the dual-stacked composite rectangular headlights, clean factory bumper lines, and rugged off-road tires emerging from the wheel arches. A perfect blend of utility and automotive culture for any garage, workshop, or classic truck enthusiast's home.

Key Features
Precision Fusion 360 Engineering: Specially optimized for FDM 3D printing, ensuring sharp lines along the aerodynamic 90s hood, crisp separation in the grille mesh, and deep definition on the tire treads.
Integrated Keyslot Mount: The rear of the structural plate features a built-in keyslot (keyhole) mechanical mounting system. This enables the truck assembly to slide smoothly over wall-anchored screws for a flush, secure, and entirely hidden installation.
Reinforced Truck-Strength Hooks: Blended seamlessly into the classic front bumper design, these integrated hooks are reinforced to easily hold heavy everyday keychains, vehicle fobs, or small workshop tools.
Printing & Material Advice
Recommended Material: Grey PETG. Because of the functional weight on the hooks and the structural requirements of the mechanical wall mount, PETG is highly recommended. As shown in the preview, Grey PETG offers outstanding layer adhesion, great impact resistance, and a solid industrial metallic finish right off the build plate.
Layer Height: 0.16mm - 0.2mm to capture all the clean geometric details of the late 90s front fascia and rugged wheels.
Infill: 20% to 25% (Gyroid or Grid pattern) for rock-solid internal support around the mounting slots.
Supports: Minimal supports are recommended under the front bumper overhangs and inside the rear mechanical keyslot pocket.
Assembly Instructions
Print: Use Grey PETG for maximum mechanical strength and premium durability.
Wall Prep: Install standard screws with drywall anchors, leaving the screw heads protruding roughly 3-5mm from the wall surface.
Mount: Align the integrated keyslots on the back plate with the screws and slide the truck frame downward until it locks tightly against the wall.
