This is the World's Smallest 3D Printed Whistle! It can reach 90+ decibels, making it perfect for emergencies, outdoor use, or just testing how much sound can come from something this small. Volume testing was done outdoors using an iPhone 12, with the whistle positioned 1 meter away from the microphone. While results may vary depending on print settings and airflow, the sound output is surprisingly powerful for its size. ⚠️ WARNING: This whistle is not a toy. It produces extremely loud sound and can cause serious hearing damage if used improperly. Avoid using near children or pets.
