BMW M4 GT4 Inspired Keychain

Bring a piece of the racetrack to your pocket! This keychain is inspired by the aggressive lines of the BMW M4 GT4. Designed for car enthusiasts and racing fans, it’s a quick and easy print that looks great in any color.

🛠️ Print Settings

This model is optimized for simple printing and durability:

• Material: PLA works perfectly (PETG or ABS also fine).
• Layer Height: 0.16mm or 0.2mm for a smooth finish.
• Infill: 15-20% (Grid or Gyroid).
• Walls: 3 lines for better strength around the ring hole.
• Ironing: Highly recommended on the top surface for a "pro" look.

Pro Tip: If you want a two-tone look (e.g., black body with white/silver details), add a manual color change (filament swap) at the layer where the logo or car details begin!

🔧 Post-Processing

1. Remove the small brim (if used).
2. Add a standard metal keyring (approx. 25-30mm).
3. (Optional) A quick pass with a lighter/heat gun to remove any tiny strings.
