Beskrivelse

A masterclass in fluid dynamics and 3D printing optimization. This micro whistle redefines the ratio between size and performance: measuring just 32 mm in length and weighing an unnoticeable 1.73 g , it manages to unleash a staggering sound output of 117 dB —comparable to the volume of a live rock concert or a chainsaw. Its flat, ultra-lightweight form factor makes it the perfect safety gadget or everyday carry (EDC) item. Add it to your keychain, backpack zippers, or survival kits without adding any bulk. 📊 Technical Specs & Print Settings Parameter Value / Recommended Setting Dimensions 32.0 mm × 8.0 mm × 3,8 mm Total Weight 1.73 g Sound Output 117 dB Print Time (Monochrome) Under 5 minutes Layer Height 0.12 mm - 0.16 mm (crucial for a sharp, clean labium ) Perimeters / Walls 3 or 4 minimum (ensures a 100% airtight internal chamber) Infill 100% (recommended for optimal acoustic rigidity) Supports None needed 💡 Design Highlights Record-Breaking Efficiency: Less than 2 grams of plastic engineered to deliver a high-volume emergency signal. Rapid Production: Prints in less than 5 minutes in its single-color configuration, making it a perfect quick print, calibration test, or mass-production item. Multi-Material Ready: The model (v4.3) features pre-split bodies, allowing you to easily print a textured, dual-color top face using AMS/MMU systems while keeping the internal air channels perfectly smooth and clean. Practical Integration: Features a robust, integrated loop to easily attach cordage, split rings, or keychains. 🛠️ Printing Tips for Maximum Loudness To hit that 117 dB sweet spot, your printer needs to be well-calibrated. Make sure your filament is dry to prevent any micro-stringing inside the air canal, and ensure the labium (the sharp wedge where the air splits) prints as crisp and clean as possible.
