8 kHz Dog Whistle
Description
**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.
