A birdhouse, also called a nest box, is an artificial structure designed to provide birds with a place to nest. 
 

It mimics natural cavities such as holes in trees that some bird species use for shelter and raising their young. Birdhouses are often used to support bird populations and can help attract birds to gardens, where some species also contribute to pest control. This one was made out of PLA, but it is strongly recommended to use PETG or ASA/ABS if it is installed outside.

I followed recommendations from various societies for bird conservation, but if anyone has another insight, I will be happy to hear it. This model does not have ventilation, but you can make a few negative parts and poke a few holes.

Assembly video coming soon, but it is very simple to assemble. You will require glue to unite the pieces.
