Here are some basic card models for you to download. You can print them out on stiff card or paper. For a glossy, more durable finish, laminate the parts before building.
I will add models as the site develops, so please check this section again from time to time.
If you have a suggestion - for example your own favourite spacecraft - please feel free to get in touch and I'll do my best for you.
Enjoy ...
Mikey
