Prints fully assembled in "flat packed" mode (what..the..?) See : http://youtu.be/bl2VTvjv_UA

Contains a perch, rain roof, ventilation, drainage, integrated hinges and is cleanable.
The hole is high enough so the chicks cannot fall out, yet they can climb up the sloped walls when ready to fly the nest.

Print without support, it's all in the geometry.
It prints fully assembled in "flat packed" mode, just open and screw to tree/board.
I have included a PARTITION.stl so you can print two birdhouses off, and attach them back to back, to make a hanging condo.
A really small footprint for a large birdhouse. If you want to push the boundaries of unattended print time then I have included an stl where 3 of these are nested (sorry) together. The total build cube required for a nest of 3 is only = 176mm x 176mm x 107mm.
