I have a metallic birdfeeder like this but this is so much easier to 3d print and it is lighter. This model is for a pole that has inside diam over 44mm. If you want different kinda clamp or different diam or whatever.. You can message me and I'll try to do my best but i ain't expert xD

I didn't need any support under the feeder but those 3 bars at feeder you have to have supports.

You may have to scale this smaller to fit entirely to 220mm build plate. You can print feeder and lid like with E3 and E5 but the storage “visor” can be too much for these printers. I made this with Elegoo 3 Neptune plus.
