Hanging Bird House / Food Dispenser

UPDATE: I created an updated version of this thing here: https://www.thingiverse.com/thing:3601996

The winters in germany are pretty cold, an in this time the birds don't get much food.

So I designed a birdhouse, which you can hang somewhere. The birds food, which is in the middle part of the house, is automaticly going to the basement, if there is no food anymore.

Hope you like it, the source is provided by a FreeCAD file and a stl.
