UTL Pool Torpedo 25 cm

# Description
This is a swimming pool toy that can be used for underwater rugby-like game. See Underwater Torpedo League. Or just play throwing.

## Materials
* Shell and fins: TPU 100% infill.
* Core: PLA/PETg/whatever heavy and stiff enough plastic 100% infill. Probably you can use TPU as well.

## Tips
* You can modify the core by adding some space for metal weights.
* The total weight of the torpedo should be about 310-315 grams. Or a bit more.
* If you choose to print fins separately, you should glue them in.
* It is a good idea to cut a ring out from middle shell in a slicer. Then you can print it in another color and change it's height a bit to adjust assembly tightness if it is necessary.

## Credits
* I was inspired by the torpedo from [Khroom store](https://khroom-sport.com).
