stackable 20 ft Container with open top and working door

this is remix from this , spliting the top cover so the door still can be used when the top cover isn't used for enabling easy access to inner compartment as this model used as hotwheels diorama and servers diorama so i need to eassy access and still maintain the front door function.   need asembly for front door and front top cover. also adding stacking point from 4 point to 6 point at top and bottom.
