**News:** For building block enthusiasts, I've created a <a href="https://www.thingiverse.com/thing:5914127"> Lego compatible variant of this whistle set</a>: <a href="https://www.thingiverse.com/thing:5914127"><img src="https://media.printables.com/media/prints/425055/images/3522524_5bfa5b92-6f63-4e8a-b654-51e80d5a1e4c/thumbs/inside/1920x1440/jpg/title.webp" width="50%" height="50%"></a> **Update 2023-03-07:** I also designed a nice low-poly display stand for the complete [Steam Train Whistle Set](https://www.printables.com/model/412666-steam-train-whistle-set) which you can download <a href="https://www.thingiverse.com/thing:5896890">here</a>: <a href="https://www.thingiverse.com/thing:5896890"><img src="https://media.printables.com/media/prints/417723/images/3471678_ea18c7ab-bef7-41c3-99cb-7f68ca8c17e7/thumbs/inside/1920x1440/jpg/display.webp" width="50%" height="50%"></a> **Update 2023-03-04:** I have designed two more variants with different pitches which you can download <a href="https://www.printables.com/model/412666-steam-train-whistle-set">here</a>. <a href="https://www.printables.com/model/412666-steam-train-whistle-set"><img src="https://media.printables.com/media/prints/412666/images/3441845_e99f7c4a-1dd6-42c8-9ad9-8a8adc5a60a8/thumbs/inside/1920x1440/jpg/set-title.webp" width="50%" height="50%"></a> **Summary:** This 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. Naturalistic sound, easy and quick to print. Less than 10 grams of filament required, only 111 x 19 x 8 mm in size. Print with 0.4 mm line width and 0.2 mm layer height. And don't print too fast, a whistle needs sharp edges. If you want a nice dual color print, change filament at layer 6 and 36. **Please also check out my new <a href="https://www.thingiverse.com/thing:5897001">Safety Whistle</a>:** <a href="https://www.thingiverse.com/thing:5897001"><img src="https://media.printables.com/media/prints/417238/images/3464192_9b3f61e5-6690-4106-8901-1dc5d7f79685/thumbs/inside/1920x1440/jpg/image-4.webp" width="48%" height="48%"></a> <a href="https://www.thingiverse.com/thing:5897001"><img src="https://media.printables.com/media/prints/417238/images/3463303_215a15f3-58bb-4f92-94e5-55c0c6caf423/thumbs/inside/1920x1440/jpg/image-3.webp" width="48%" height="48%"></a>
