Soda bottle bird feeder (remix)

I printed two of the original feeder and the birds were ignoring it and using our other feeders. The base and perch seemed too small. I used meshmixer to reduce the original stl, then expanded the base with F360. Instead of printing a perch, I drilled then looped some wire through the perch holes. I was going to insert some small branches but doesn't appear necessary as the birds love this version.

Unfortunately, I changed three variables and I'm not sure exactly which were important to the birds. But night and day difference between the bird attraction.

1. Size of the base and perch.
2. Filament changed from orange ABS to grey PETG.
3. Food changed.
