Simple model of the Chinese Tiangong-1 Space Station. Glue the sections of the service and science module together. Use the 15mm pin to attach the solar panels and to mate with the matching Shenzhou space capsule.

This was originally published on the Autodesk 123D site, but that is gone now, so here it is. I've made multiple changes to improve printability and tesselation.

Refer to these instructions for assembly, in particular the bit about aligning the Shenzhou orbital module with the solar panels on Tiangong.
