Lego Compatible Whistle

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.
