Been toying a bit with some 3d modelling a while back.
Plan is to get them indeed cast eventually. I'll probably have to redo these because they were never designed with printing or casting in mind (from a technical point of view). So the idea is to keep the same form/idea, but in a way that it's printable and easy to cast.
Ive been on some of the bigger companies that have been mass producing BFG ships, to start making more Ork ships...especially some of the Battleships....but I cant get them to do it!!
