Chickadee Bird Feeder

We're encouraging Black Capped Chickadees to call our backyard home. First there was the Chickadee Condo. Then the Bully Birdie Barrier. Now we need a bird feeder that only they can utilize, with entry holes 1 1/8". Chickadees are frequently chased off by larger birds such as sparrows or finches. This bird feeder limits birds to chickadee sized birds. Chickadees love black oil sunflower seeds. They will quickly grab a seed and fly off to a perch where they hold the seed with their claws and quickly crack the seed shell and nibble away at the seed.

Nothing special about printing, other than PETG will be UV resistant. It's modular and designed to print without difficulty. (although the support arm length is 280mm and printed diagonally might squeeze down to 220mm plate). I printed on an OPXL5H. I used a 3mmx15 screw to attach the bottom support arms and a carabiner for the top hanger.
