The model is based on SpaceX's official datasheet (.pdf) for the Dragon spacecraft. The model features the trunk section and solar panels, the capsule, as well as the inner pressure hull. All of the parts are made in components to allow others to modify and move around easier. It lacks many of the details and accuracy found on the STL file, but I hope it gives SketchUp users something to start with and improve upon.
