A miniature version of emmet's Apollo Mission. To make the model printable at this small (30%) scale, I have:

• Reinforced the spindly lander legs.
• Made the rocket nozzles solid.
• Combined the service ring with the service module (adding some support following the lines of the radial beam trusses so that the service module can print without support -- see http://pics-about-space.com/apollo-service-module?p=4#img15413448471077531127).
• Replaced the pins with built-in pegs.

The ascent module does need to be printed with support. All other parts should print without support.
