I have now added V2 to reduce leaks. I tested  for a few days and it looks really good.

This is a Hummingbird Feeder I designed to use empty “Sport Drink” bottles as the reservoir for the Hummingbird Feeder. It uses a 591ml (Canada Standard) brand name sport drink bottle as the reservoir and the bottom screws directly on also the top bracket just snaps on so there no glue/screws or additional parts required. Re-cycle/Re-use your drink bottles as Hummingbird Feeders. They love it!!!

I printed in PETG and would suggest to do so, other materials also could be used as long as they are recommended for outdoors..

You can make your Nectar: 4 parts water to 1 part sugar bring to a boil, stir a lot to dissolve the sugar, let cool and pour into the feeder.

Please comment if this works with "sports bottles" from other areas than Canada? Maybe it fits others, but I can't test.

I also have uploaded a Bird Feeder that uses the same bottles  [https://makerworld.com/en/models/595429#profileId-517343](https://makerworld.com/en/models/595429#profileId-517343)
