Steam Train Whistle (Building bricks compatible)

This new variant of my building bricks compatible Steam Train Whistles produces a very realistic and even deeper sound. I optimized the design for better bridging. There are two versions, with and without eyelet.

I have also designed other members of this whistle family:

• high pitched whistle,
• medium pitched whistles.

How to print:

Print with 0.4 mm line width and 0.2 mm layer height, 7 top and 7 bottom layers. And don't print too fast, a whistle needs sharp edges!

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.
