PET-Kanne

Accessory which turns a regular plastic bottle into a plant watering can, or drinking water tap.

If you use it for drinks, make sure you print this with something food safe. PLA and ABS is generally not considered to be safe due to the unknown pigments used for coloring.

This thing has a PCO28 screw thread, which makes it fit the regular 0.5, 1 and 1.5 liter PET plastic bottles sold in Europe. I don't know if plastic bottles in other parts of the planet are the same. Also, I don't know if it would fit glass bottles.

It features a separate channel for air inflow, allowing the liquid to come out quicker and continuous

I call it PET-Kanne in reference to the German word Gießkanne, but made from PET (http://en.wikipedia.org/wiki/Polyethylene_terephthalate) bottle
