Fast Flow Bird Seed Funnel

Fast Flow Bird Seed Funnel

Instead of using a funnel that fits inside the neck of the bottle, this funnel screws onto its outside thread, thus allowing far greater throughput of seed.
Being screwed on, the funnel has the further advantage of not swinging around all over the place whilst you are trying to pour seed into the bottle.

This is designed to work in conjunction with the ‘Rain-proof‘ bird feeder which may be found here:- https://www.thingiverse.com/thing:4686734h
