This is a screw on lid that turns your standard mouth mason Jars in into a bird feeder. The hanger was made with bailer twine that happened to match my filament color.
Forgive the macramé job, I was winging it.
Updated: I would suggest using V2. I found the time to add a lip to each of the outlets so that the seeds don't fall out.
Thanks @Radish_256693 for finding this video on how to do the tie the hanger.
The author remixed this model.
I just used my mason jar ring as the thread to do this design. The majority is new.
