For ROTOSCAN's Space Shuttle on launch pad model.

For the aft section of the orbiter I reversed one face on the wing section and several faces on the tail. This should slice better for people having trouble printing this section.

For the mid section of the orbiter I added a peg hole for attaching to the external tank. Hope it's in the right place.

For the fore and aft sections of the external tank the peg holes didn't print right for me. I fixed them by inverting a few faces in the STL.

On the forward part of the fuel tank, the "intertank" section with the hat stringers didn't print well for me because the stringers are too small for my makerbot resolution. So I smoothed them out in the STL file. That was tedious.

For those of you who don't know, this part of the external tank wasn't really a tank. It didn't have liquid inside. Instead it was the transition between the hydrogen tank below and the oxygen tank above. And it carried the thrust from the solid rocket boosters which lofted the tank. So it had to be stiffened with extra stringers.
