Bird Feeder Ventilation Cone

I recognized, especially in the wet month of the year, bird food gets gunky and sticking together in the middle/bottom of the feeder. Even when it is dry, the seeds in the middle will not fall out unless you shake the feeder around a bit.I designed this simple cone to go on the middle rode and guide the seeds towards the edge. It has small ventilation holes to provide some airflow, at least, if you drill some holes in the bottom of the feeder (shown in pictures).As I saw this feeder at several places from discounters to hardware stores, there might be someone on makerworld needing this.
