This is a concept design for a cross gantry 3d printer, notice that it's not functional at all and far from ready to be printed. it utalizes linear rails and 8 motors for the gantry. I havent designed a bed at the moment but it will probably be simple when it comes. There are certain design flaws like missing screws, the belts colliding with the frame and much more which will be fixed in the near future.
