Ok, FWIW, I ran the "repaired x2" STL file from the .zip through makerware's slicer and it seems like it'll be printable with that slicer as well. (I had to shrink it). Microsoft 3D Builder also looks like it'd print it.

PS: It's too fat for most beds @ 1:1, however Microsoft 3D Builder does a good job of chopping models in half, you can then reexport the halves to STL for other print software if need be. (It also does a good job or repairing some files.)
