Bird Feeder Funnel

I wanted a simple funnel that would fit my bird feeders that would allow me to fill them up with seed quickly and not make a mess. The other designs on MakerWorld were not quite right for the job, so I created this simple one. I can now fill up the feeders quickly without spilling seed everywhere.Not the more exciting print or design, but it is functional. So I thought this might be of interest to someone else.I am sure it can be resized to meet different sized diameter feeders.
