Connects two 2-liter bottles to allow you to make a Tornado. Thread fittings are the US standard 2-liter bottle threads, PCO28 1881. Should fit other bottles with a nominally 28mm OD and a 2.7mm pitch.
Originally designed to use a -020 O-ring (1" OD) for a seal on the bottle mouth but apparently doesn't really need it, at least with the coke bottles I tested it with.

Needs to be printed with supports. PLA worked better than PETG for me because it is easier to remove the support material from the O-ring groove.
Flip the bottles over and give the bottles a swirl to create your own "tornado".
