This is a roof part for prusament spool birdfeeder by RT3D Workshop.
The original model risks getting the fod wet and causing disease to birds. This is simply an extension with soda bottle threads, no gluing is needed.
The original model has rather half-baked lug for hanging the feeder. It's better to drill few holes through the bottle, pull the string through and then seal these holes with glue.
Always follow local ornithological society recommendations when feeding wild birds!
