This was my entry for the Birdhouse Challenge competition http://www.thingiverse.com/challenges/birdhouse - its a home for a millenium falcon
The STL files print a sphere 100mm in diameter. Suggest scaling up to the size you need - the full size is 160km diameter - make sure you cover the thermal exhaust port after printing
There's also a version remixed as a christmas tree ornament here http://www.thingiverse.com/thing:117733
Solidworks source files are included - go nuts!
Print out the hemispheres and glue together - use a 5mm ring bolt through the top to hang outdoors.
The laser isn't really meant to be printed - its just for show (but feel free to remix it if you want to print the whole thing)
