After looking at all the birdhouses here I found that a lot take 7+ hours to print and use a good bit of filament.
So I designed this basic bird house. Print with 2 shells, 2 layers top and bottom. Made to be screwed into a surface.
Lay "floor" of birdhouse on bed and print. Scale up or down to your needs.
Takes about 3.5 - 4 hours to print.
