Bird feeder with a normal plastic bottle

thingiverse

I printed bird feeder from "gavinkennedy" but I need some changes now. So I created a new version. I reduced the amount of material, made a smaller water drain hole at the bottom since seeds were passing through it. I also designed a smaller roof, which serves mainly as an aesthetic addition. The hanging hook is screwed to the bottom of the bottle with a small screw. I used a tiny 0.5-liter Coca-Cola bottle. 02/12/2019 I added a coupler that Vijit proposed and designed. Thanks Vijit for a great improvement!
