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 and I don't actually remember what I did. I think it was a bottle carrying knot on the bottom www.animatedknots.com/bottle-sling-knot and then just reef knots where the ropes cross. If the tying isn't your thing then donpeek remixed a nice attachment for hanging it. https://www.thingiverse.com/thing:6104036
