Bird feeder using a large 750ml true fruits smoothie bottle as a food reservoir. The larger bottle neck prevents bigger pieces like dried berries from clogging up the feeder.
Prints fine with 0.3 mm layer height; supports might be needed for the tabs that thread onto the bottle, everything else should be fine without.
Some rope or twine is needed for assembly and hanging the feeder
