Bottle Vortex

I was browsing Printables and found a library for bottle threads called [PET bottle PCO28 1810](https://www.printables.com/model/262018-pet-bottle-pco28-1810-thread-standard-models/) thread standard models by steffanders.

There should be a silent-yet-obligatory rule in the community that any time a new bottle cap threads library comes out, a vortex bottle generator needs to be created with it.

## Printing

It can be made with PLA, but PETG is recommended. In the video, PETG is used.

There is a version with support built-in and one without supports. The outer support ring connects to the cap's seal ring - make sure not to damage the seal ring (although I don't think it's possible to do so by accident unless you get carried away using violent force).

## Parts

This thing also requires two 2-liter bottles that use the standard cap threads. In the video, Diet Coke bottles are used because of their clarity.

## Assembly

1. Tear off labels
