SpaceX Interplanetary Transport System

This is a remix of Zastro's great model.

* I joined the two halves of the body together and cut it near the engines - much easier to hide the seam there. Body prints upright as one piece.

* Engines and legs are now printed separately.

* Fixed the scale of the model - the original would import at a tiny size. Assembled with legs it stands close to a foot tall.

* Added holes for 1/8th inch guide rods (optional) to make it easier to line up the halves

Requires glue for final assembly.
