Hello,

I’d like to introduce my bird feeder station.

Before designing this one, I tried several other feeders, but they all had issues. Some were too small and therefore hard to clean, others had no drainage holes at the bottom, which caused water to collect and turn the food into a mushy mess, and some simply weren’t stable enough. That’s why I decided to create my own version.

This feeder is very well accepted by birds  maybe even a little too well, since I’ve already ended up buying a 25 kg bag of bird food.

Assembly is quite simple. You’ll need a 1.5 L Cola bottle. Near the top of the bottle, carefully make two small holes opposite each other using a knife and click the holder into place as shown in the pictures. 

If you’re concerned about water getting into the system, you can also seal the two knife made holes with hot glue. 

After that, fill the bottle with bird food. For this step, I designed an extra funnel that screws directly onto the bottle, making refilling much easier and cleaner.

Finally, screw the plate onto the bottom and hang up the feeder.

It usually takes about a day for the birds to get used to the station, but once they do, I can guarantee there will be a lot of activity.

I’d be happy if you shared photos of your well-used bird feeder stations!

Update January 19th 2026:

I have added the print profile for version V2.

I created this modified version of the bird feeder because some users experienced issues with larger grains. The main change was removing the internal supports that previously allowed the bottle thread to be printed without additional support structures. This modification enables larger grains and a higher overall amount of feed to flow out of the bottle more easily.

Additionally, I increased the height of the rim, which was necessary due to the increased feed output. I also closed the hole at the bottom, helping to reduce overall printing time.

Please note that version V2 is not necessarily better than the original one. Personally, the first version still works perfectly fine for me. However, if you are using larger grains or had issues with the original version, V2 might be the better option for you.
