Soda Bottle Bird Feeder

A bird feeder that uses a 2 liter soda bottle to store the bird seed. Seed automatically dispenses into the tray and refills as the birds eat the seed. The tray screws onto the bottle just like putting the cap on. The hanger ring requires six #4 sheet metal screws .375" (9.5mm) long. You can tie fishing line or string onto the hanger ring (refer to picture) to hang the feeder from. I would suggest painting or using spray clear on to protect the tray from the weather. There are drain holes in the bottom of the tray, depending on the tolerances of your printer you may have to drill them out after printing.
