Keychain Whistles (Building bricks compatible)

Update 2023-03-17:

I've added a lower pitched variant of this whistle.

Summary

This is a fancy variant of my Keychain Whistle that fits common 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 whistles require 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.

If you have printed this design and you like it, I would be happy if your make is uploaded.
