My another try for exporting ship from videogame. This is my small Comat pod.
This model isn't tested on any printer yet.
Model from videogame
Space Engineers is surivial/creative game in space where you can build spaceships, bases, asteroids, planets with blocks or voxel. These things can be extracted in to OBJ file and than converted in to STL. In theory i could print my own ship.
