To follow-up on my post below: I fixed the "inside-out" owl problem and did a successful test print using MakerWare and an MBot Cube 2. I posted the updated STL files at the following link: http://www.thingiverse.com/thi.... If you are using MakerWare, download *that* STL file.
For those with MakerWare issues: the right owl has inverted normals -- they're all facing inwards. So each "outer" surface of the female owl is interpretted as an interior surface. This is why it shows up weird in MakerWare (it's displaying the interior of an object), and it doesn't print properly, because it's not sure what to do.
I loaded the STL file in Blender and was able to verify this is the case. All I had to do was select all the faces of the right owl (switch to orthographic front-facing, numpad-1, numpad-5, and then 'b' for box select). Then on the left-menu there is a button for "Normals -> Flip Direction". Once I did that, I re-exported to STL and it looks fine in MakerWare. I haven't tried printing it yet, but if it works I will upload the updated STL as a derivative of this one.
I had this problem with some simpler models that I made in Blender: I created some surfaces/objects, but some of the normals were facing the wrong way and MakerWare freaked out and printed garbage. If you are making a model in Blender, you can switch to edit mode, open the properties menu ("N" key), select the "Normals->Show Face" button, and then set the size to 1.0 or higher. Any outer surface of your model should have the normal extending outwards into open air, not into the model.
