Humming Bird Feeder - Mason Jar Design

thingiverse

So with the dry weather that we have been having the humming bird feeder was needing to be filled twice a week. I had thought that I could design a feeder with a large (1 litre) Mason Jar that would take the hummingbirds a while to get through. The design is for a 70mm (2.75") mouth opening. I beleive this is regular size and not "WIDE MOUTH" Since the jar hangs upside-down.. it took me a while to design an accurate enough thread fitting to prevent leakage. but I finally acheived that...Enjoy By the way.. it is pretty much imperative that you use ABS.. since it is resistant to liquids There are two files, one for the feeder bottom, and one for the support ring. The support ring goes onto the neck of the mason jar before you screw the bottom on. As you can see by the photo.. this has a string run through it for hanging.
