🏁 Racing Helmet Keychain — V2 A piece of the track on your keys 🔑

Mini full-face helmet with an opening visor: print-in-place hinge, clips shut in two clicks, no glue ⚙️

What changed from V1 ⬇️

🔧 Hinge — V1: cut 1.75 mm filament, heat it and shape it by hand. V2: press-fit, click click.

🪖 Shape — was narrow and stretched; now true to a real helmet.

💨 Air vents — before just engraved lines; now raised, with a color change that makes them pop.

🕶️ Visor — before: supports across the front, poor plate adhesion and visible layer steps. Now: prints flat, supports on the hinges only, clean straight front.

✨ Hinge finish — thicker and better refined.

🏎️ Spoiler — before a flat shape; now a real spoiler.

🧩 3MF files come ready with supports and settings: load, print, nothing to touch.

📸 Improvements visible in the photos and in the V1→V2 comparison board.

💡 Visor in translucent filament for a “glass” look, or matte black for a tinted-visor effect.

🎨 Endless color combinations.
