It's tiny but still pretty loud and also doubles as an emergency whistle. Attach it to a necklace or keychain, or use it as a charm for a gift wrap or backpack. **How to print:** Print with 0.4 mm line width and 0.2 mm layer height, 5 top and 5 bottom layers. No support required, place the Z-seam near the mouthpiece. Print slowly to get sharp edges - this makes for a nicer tone. if you want a 2 color whistle, change color for the top 3 layers. **Please also check out my [Compact Emergency Whistle](https://www.printables.com/model/394669-loudest-whistle-for-your-keychain).**
