I like this style of hummingbird feeder because they're cheap and found that we were wasting a lot of nectar with larger ones. These small ones however don't often have a perch included. I created a makeshift perch using some thick wire and noticed they stay and feed for a lot longer, which inspired me to make this design.

The .f3d file is fully parameterized. So if you don't have the exact same feeder you can easily adjust it to your needs.
