3d printer mouse pad

I design this model to be printed without AMS in two colors. I was trying to experiment how to do it and I have this idea where you just print the first plate in one color and the without remove the print you start printing the second plate on top. both prints aling perfectly to make a single even one without having to depend on a AMS and also reducing the purge filament and waste to the minimum.   IMPORTANT: to have a successful print dont move the prints on the printer or slicer because the are perfectly align. and also is highly recomended to use 0.2mm layer high so the slicer does not mess with the two prints.   Also the all design is oriented with the upside down so the mouse pad have the texture from the bed to work better with the mouse. I just recomend after adding some bluetag or glu some pieces of rubber on the base of the mouse pad to stop it from slide off the desk or table.
