The file 'Roof Extension For Bird Feeder (Dove Protection…) 3D Printer Model' is (stl) file type, size is 917.0B.
My neighbour told me that he has seen a clever Dove ("Air rat") that managed sitting on top of the roof picking corn from my bird-feeder: https://www.thingiverse.com/thing:4045573
or made by me: https://www.thingiverse.com/make:803151
This bird feeder should only work for little birds...!
So I created a roof extension and glued it to the original roof. Hope it works.
