Big functional bird feeder

This is a large scale bird feeder I made to meet my bird feeding needs. I have a lot of birds so I wanted a feeder that was high capacity. This model allowed me to keep the feeders full at all times. I wanted a feeder that protected the seeds from rain and had drain holes. (No moldy seed).I wanted it to be easy to fill, so no screwing on tops. Trying to do that in the cold in gloves is terrible! So simple string through the middle, with a deep grove for the lid to fit into.I wanted the tube to be able to be printed in a clear filament, so I could see the seed level. Thus this very simple feeder evolved. I have added perched, but they are very optional and strictly experimental at this point. I printed in PETG to allow for UV resistance. I would love feedback. I know it's a big time/filament commitment!
