When I was printing ships and starbases for 1st edition of Eclipse, I found some usable ships ( https://www.thingiverse.com/thing:3141223 ), but not many usable starbase (only 3) designs to have a different one for each race. So I decided to create some designs of my own.

Print 4 of each starbase, with same filament color you have used to print that race's ships.

Attached is OpenSCAD source for all the models. Note that pirate_base.scad is generated (with some randomness) from stargen.pl (perl script) and stargen_base.scad. A nice variant is already pre-generated and included.
