Added a round perch.
This is an updated version of this https://www.printables.com/model/12258-bird-feeder-bottle-20
Here is a bird feeder to screw on the bottom of an apple juice bottle you buy at Walmart https://www.walmart.com/ip/Great-Value-100-Apple-Juice-96-oz/10415325. This is big enough for whole (black shell) sunflower seeds to be used. There are holes in the base to allow rain water to escape.
This has no base and the bottle needs to be hung. Punch a hole in the top and put a string or anything to hang it. The bottle will need some air flow on the top sides to stop condensation from forming on the inside and getting the seed wet. The perch is short so that a dove cannot sit on it as doves just look for sunflower hearts and spill the black shells.
