OpenSCAD model of a wooden train whistle. This is based fairly closely to a two barrel wooden whistle. I have not printed this so I don't know if it works yet.

The OpenSCAD file contains two settings to change the number of barrels you would like (1, 2 or 4) and internal hole length variance


Print, hopefully make train sounds. chugga chugga CHOO CHOO

I would suggest a 10-20% infill setting, however that hasn't been tested.

I printed it, but only one of the whistles worked if you blew really hard. It could be my print settings, but even after a little filing it didn't work.

I was annoyed to find out that none of the holes come close to the end, so a lot of plastic is wasted making this whistle longer than it needs to be.

You can see the final product in my "I made one" image, and here is an image of it in progress:


D'oh! That's what I get for sitting on a project! I was copying the wooden one here:


I like in your design you have a smaller mouth piece. As this is a work in progress there is always room for improvements.
