The original model (and the one attributed to Tobz) was created by sgillford_at_gmail.com. I made numerous modifications to make it printable.
I used NetFabb and Microsoft 3D Builder to create and error-check the parts. Although not yet fully tested, they are fully manifold and should be printable without issue.
With that said, the parts all require support, which may prove challenging to remove.
I recommend printing the top and bottom shell pieces in yellow and the interior (and optional lower hatch) in gray or silver.
The picture is of my first printed version (made solid with MeshMixer, then printed with 0% infill and 3 shells in GP3D Yellow PLA on a Replicator 2), with the interior details and lights Photoshopped in. This inspired me to actually produce a detailed interior. The hatch on the bottom is separate, and covers a hole for a display stand (like this one: http://www.thingiverse.com/thing:1299040). It might also look good emerging from a splash like this one: http://www.thingiverse.com/thing:192007.
The lower shell has holes for lights and there's plenty of room inside the shell for the necessary wiring, so go for it!
The chairs and people shown in the photo are not included.
July 31 update: Incorrectly sized parts have been fixed. Also, an error in the bottom shell has been fixed. A one-piece model has also been added. Print the one-piece model as shown in the last photo with 0% infill, 3 shells, raft and support ON.
