**News:** I have designed many whistles, you can find them in my **[Whistle Collection](https://www.thingiverse.com/threed-michael/collections/37167385/things)**. These are just a few of my latest designs: <a href="https://www.thingiverse.com/thing:6266643"><img src="https://media.printables.com/media/prints/615908/images/4887750_7a4d8691-36cc-49f9-a605-38757bd3c21a_a9ad857b-2aff-4aa9-8df3-94dd0388fe4b/thumbs/inside/1920x1440/jpg/title.webp" width="32%" height="32%"></a>  </a><a href="https://www.thingiverse.com/thing:5897001"><img src="https://media.printables.com/media/prints/417238/images/3464192_9b3f61e5-6690-4106-8901-1dc5d7f79685/thumbs/inside/1600x1200/jpg/image-4.webp" width="32%" height="32%">  </a><a href="https://www.thingiverse.com/thing:5914127"><img src="https://media.printables.com/media/prints/425055/images/3522524_5bfa5b92-6f63-4e8a-b654-51e80d5a1e4c/thumbs/inside/1920x1440/jpg/title.webp" width="32%" height="32%"></a> **WARNING:** This is an emergency whistle and not a toy! It's extremely loud which can harm the ears, so please protect your ears and don't use it near other people or animals! **Update 2023-03-24:** I've designed an even louder, lower-pitched variant of this whistle that you can download **[here](https://www.printables.com/model/430499-tiny-emergency-whistle-incredibly-loud)**. **Summary** This keychain compatible emergency whistle is a variant of my big **[Emergency Whistle](https://www.thingiverse.com/thing:5897001)** - much smaller, but almost as loud as it's big brother. **How to print:** **All Slicers:** Use a line width of 0.4 mm and a layer height of 0.2 mm, 5 top layers and 5 bottom layers. Don't use support and don't change the given orientation of the object! The whistle requires correct positioning of the Z-seam - it shouldn't be placed in the narrow air passages inside the whistle. The Z-seam should be positioned as shown in the images above (the white dots represent the Z-seam). Use the “Z Seam Alignment: User specified” option in Cura or the "Seam Painting" option in PrusaSlicer to achieve this. Print slowly to achieve sharp edges (max. 30 mm/s for walls). **PrusaSlicer:** Use default settings and manually paint the z-seam as in the pictures above. **Cura Slicer:** - Wall Line Count: 2 - Extra Infill Wall Count: 1 - Z-Seam Relative: ON - Z-Seam X: 0 - Z-Seam Y: -50 - Enable Bridge Settings: ON - Bridge Wall Coasting: 0% - Bridge Wall Flow: 100% - Bridge Skin Flow: 70% - Bridge Has Multiple Layers: OFF **Do you like it?** If you have printed this design and you like it, I would be happy if your make is uploaded.
