This is a simple birdfeeder for smaller birds.

Printing this is fairly simple. I have used a layer height of 0.25mm and it cam out decent. You can try to print it in one piece by flipping around the whole model. When I tried, I did not use a wide enough brim so it came loose from the build platform. Since I was in a bit of a hurry I quickly created a split version, which is way easier to print. I used supports for the brim of the little roof but I guess if you use a high enough resolution you might get away without supports.
