About this 3D model
Here's a recreation of the Google Maps "pin" as a birdhouse for the MakerBot Thingiverse #Birdhouse Challenge. I've included the complete version for reference only. You should print the base first, then the 2 front pieces. For those with dual extrusion, you could probably merge the 2 front pieces into 1 file... Enjoy PS - Added a perch, one could drill a small hole and glue it in, or possibly combine with the front and extrude it straight out, up to you.
