4-Tone Quad-Chamber High-Decibel Whistle
This is a compact, high-performance whistle engineered with four distinct acoustic chambers. It is designed to maximize volume and create an attention-grabbing, multi-tonal sound signature.
Features
Quad-Tone Output: Produces 4 different frequencies simultaneously to create a dissonant, piercing chord.
Extreme Volume: Reaches over 110 dB, making it highly effective for emergency signaling and outdoor survival.
Pealess Design: No moving parts to freeze, jam, or degrade over time.
Integrated Lanyard Loop: Features a robust hexagonal loop on the rear for secure attachment to keys, packs, or paracord.
Print-in-Place: Fully optimized for 3D printing without the need for internal supports.
Recommended Print Settings
Material: PETG or ABS/ASA (for superior outdoor durability and UV resistance), though PLA works fine for general use.
Layer Height: 0.2mm or finer (critical for clean internal sound ramps and crisp edges).
Infill: 20% to 30% (gyroid or grid for structural rigidity).
Walls/Perimeters: 3 to 4 walls (ensures the airtight seals required between chambers).
Supports: None required.
