3D model description

Update 2023-03-17:
I've designed lower and higher pitched variants of this whistle.
You'll find this additional variants here.

This Lego compatible steam train whistle has only 2 tubes. However, the choosen geometry generates suitable overtones that ensure the realistic sound. The whistle can be blown softly or loudly.

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.
