8 kHz Dog Whistle

thingiverse

**WARNING:** This is a dog whistle whistle and not a toy! It's very loud which can harm the ears, so please protect your ears and don't use it near other people or animals! This compact dog whistle produces a very loud tone of about 8 kHz. It may seem quiet to you, but that's because humans (especially in old age) perceive higher sounds less loudly or not at all - unlike many animals! **How to print:** Use a line width of 0.4 mm and a layer height of 0.2 mm, 6 top layers and 6 bottom layers. 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 image 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. **Do you like it?** If you have printed this design and you like it, I would be happy if your make is uploaded. **Please also check out my latest whistle design:** <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>
