FREE Deep Space 9 Station...
Surfing the internet, found this picture...
apparently you can download the parts for free, print them and build this completely in paper.
I haven't tried this (particular model) yet, but I immediately thought of my fellow modelers here on the forum.
Here you should find the parts for the model :

It may be not as detailed or accurate like a resin kit, but I guess one could have fun building it
Have fun...
