123D Shuttle Rocket with Connectors

This is a remix of the Shuttle and Booster Tank from the Autodesk 123D Gallery. They are interesting (albeit somewhat fanciful) models, but there was no way to connect the two together!
I modeled a set of sliding connectors (female and male) and integrated them with the shuttle and tank using Tinkercad.
Since I was doing it, I put a connector on both sides of the booster, that way you can launch two shuttles at once.
