Bird house

This is only my second 3D design ever, but I think it turned out very well. This bird house can be used in bird cages and aviaries for zebra finches and comparable bird sizes. The bottom is shaped slightly cupped, to center the eggs. Lid is removable for easy cleaning.

All comments and suggestions are welcome. Feel free to use and print, for as long as you publish a picture of birds nesting in it. ;-)
