PET Bottle Bird Feeder

thingiverse

I created this bird feeder for the birds tweeting outside my apartment complex to reuse some of the soda bottles like Coca-Cola, Mountain Dew and Fanta. I made it so that it fits on any PCO 1881 neck finish standard threaded PET bottles. Model Notes: Bases with varying holes are included in case you need to print whatever suits your bird feed. The small hole versions comply with most standard bird feed mixes. The "Augment" file helps adjust the hole opening on 3 & 4 large hole versions if you want to change it to a small hole without printing the whole part again. It simply inserts into the current design, saving time and material. A 4 hole clamp goes on top of the bottle for attaching twine or threads to hang it. Sling the clamp onto the bottle and shut it close using a small cable tie as shown in the pictures. I pictured some butcher's twine of 16 ply strength. If you don't have a suitable location to hang, you can print the hanging stand included in the files and attach it with a strong tape. All parts print without support.
