About this 3D model

This is a circular birdhouse with a slanted roof and a perch. I designed it so that it would use little material, and print without supports. The entrance hole diameter is 40mm, and the interior is 110mm in diameter. You could scale it to your required size, if you want to house smaller or larger birds. There is a mounting bracket with two screw holes on the back, and a loop for hanging on the top.
