MAXLancer (import/export for 3ds Max)

[Treewyrm]

So, if I see that right: this is a program I can use to model ships with without downloading milkshape3d or blender?

Nope.
It's a plugin for 3ds max (commercial product).

If you don't have 3ds max with this plugin then you can use other modeling software to create mesh and export it into .fbx file and ask a person who has 3ds max to assemble and export it into Freelancer model format (.cmp/.3db + .sur).
Alternatively there's collada importer in lanceredit (part of sdk), however it has limited functionality.
