PET Bottle Bird Feeder

PET Bottle bird feeder fits on any PCO 1881 neck finish standard threaded PET bottle like most soda bottles like Coca-Cola, Mountain Dew, Fanta, etc. I created this for the birds tweeting outside my apartment complex in the hope of reusing some of the soda bottles. :)Model Notes:Bases with varying holes (3 or 4, large or small) are included so you can print whatever suits your bird feed. The small hole versions will comply with most standard bird feed mixes.The "Augment" file will help you adjust the hole opening on 3 & 4 large hole versions in case you want to change it to a small hole but don't want to print the whole part again. It simply inserts into the current design. This saves you time and material.The 4 hole clamp goes on the top of the bottle so you can attach some twine or threads to it for hanging.
