Mos Burger Official STL data isn't include Cheese! This MOD is add cheese! 

Print it with PLA. Once printed, heat the heatbed to 80°C and place it on it. Once it's warm, place it in the Mos Burger you printed beforehand and bend the corners to make it look delicious. If you heat it above 80°C, it will look more like melted cheese.
