I previously made a mason jar bird feeder. But my wife found a bigger jar at the thrift store but it had a wide mouth. So I redesigned the feeder to work with wide mouth mason jars and made it all around bigger. To make sure it fits on the print bed I made the perches separate. Which has the nice side effect of letting you print them in a nice contrasting color. This time I built four loops into the collar to make it easier to tie to and I added an attachment point on the bottom so that you can hook a smaller bird feeder to the bottom for even more bird feeding fun. Enjoy.
