Lego Compatible Whistle

**Update 2023-03-17:** I've designed a lower pitched variant of this whistle. You'll find this variant [here](https://www.printables.com/model/425185-keychain-whistles-lego-compatible). **Summary:** This is a variant of my Keychain Whistle which fits Lego (and probably other) building bricks. **How to print:** Use a line width of 0.4 mm and a layer height of 0.2 mm, 7 top layers and 7 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. If you want a multicolor print as in the picture above, change filament at the desired height. **Do you like it?** If you have printed this design and you like it, I would be happy if your make is uploaded.
