The file 'Twilight Imperium Tribes Of Yssaril Flagship 3D Printer Model' is (stl) file type, size is 169.3KB.
I made a simple Yssaril Tribes flagship figure in TinkerCAD, based on the depiction of their flagship in Embers of the Imperium and Corrupted Space.
I printed a different little oval base to glue it onto.
