EDC Survival Whistle

I optimized this model using an Anycubic profile because, among all the whistles I have printed so far, this is one of the loudest and most powerful in terms of sound performance. Two versions are included with different lanyard attachment designs, allowing you to choose the option that best suits your needs. Print Settings * Recommended material: PLA+ * Supports: not required * Recommended layer height: 0.20 mm or lower The profile uses the Arachne wall generator, which improves the accuracy of thin walls and the internal air channel, resulting in a cleaner and more powerful sound. For the best acoustic performance, I recommend not increasing the layer height too much, since the precision of the internal channel directly affects the whistle’s sound quality.
