Simple Zip Whistle

The Zipper Whistle

The Zipper Whistle is a 2.4-gram powerhouse remixed for maximum output and instant access. I’ve integrated high-performance acoustic DNA into a rugged zipper-pull profile that screams at 120dB+. It’s designed to live on your jacket or pack; invisible until you need to be heard. This model is an adaptation of Timcel's design, which you can find here.

Design Highlights 📍

• 120dB+ Output: Re-engineered internal geometry produces a piercing, high-frequency blast that cuts through wind and ambient noise.
• Zipper Pull Integrated: Replaces standard pulls for seamless, no-fumble access on jackets, backpacks, or lanyards.
• Optimized Profile (2.4g): Engineered for "gram-shaving" EDC kits. You’ll forget it’s there until it’s time to signal.
• Fast print: Less than 17m.
• 3D Optimized Internal Geometry:
  • No Supports: Designed for clean internal airflow right off the plate.
  • Print-to-Play: Precision-angled chambers ensure a crisp, consistent tone without post-processing.
