A while ago, my son saw a toy volcano in an advertising brochure and I thought: we can do that too, but better.

So here it is: a volcano to put on your wooden train tracks, it even fits on a 180x180 printer (though you have to sink it in 1mm)

Update: I've included a solid version of the vulcano without any openings for electronics.

You can put some electronics in it for special effects, there's also a connector for a smoke generator and an internal pipe that leads the smoke up to the top.

Here's a small BOM if you like to choose the same components:
* SparkFun LiPo-Charger/Booster, 5V/1A
* LiPo Akku, 3,7V, 500mAh, 2 Pin JST Connector
* Adafruit GEMMA M0
* Adafruit NeoPixel Jewel 7x 5050 RGB 
* 4x m3 threaded inserts
* Screws: 2x m3x20, 2x m3x12 
* Mini Switch 9 x 13 mm
* USB-C 2 wire connector

As a smoke generator I can highly recommend a costronica pocket smoke, which works very well. Just make sure you don't use a water vaporiser, as the smoke will go through the circuit boards. 

But it should also be enough space inside to just put a few LEDs inside and some cotton wool on top - that would be the less overengineered edition ;-)
