Spaceship corvettes Free 3D print model

You get three classes of corvettes for fictional Inkati race. You also get three types of weapon systems. Dual gun turret, Torpedo and Missile launcher which can look large for this models, but bare in mind that these ships are practicaly enlarged fighters, the tiniest interstellar ships in Inkati fleet. You also get some additional hull mountable modules for decoration purposes. I've modeled these ships expecting for them to be printed very small, about 3 cm for smallest and about 4 cm largest, hence low details and unpollished hull.
