I have come up with a solution for 3D and two tier cakes that works perfectly. For instance, if my bottom tier is going to have a 14" board, I buy a 14" box that is 14x14x6". I then measure my cake to determine how high it is going to be and then add about 2" additional to that measurement. So, if my cake height measurement ends up being 12" I cut the side flaps of the top of the box at 6" to come up with the 12" height (6" of the bottom side of the box plus 6" up the side flap from where it connects to the box). Make the cuts on both side flaps of the top of the box. Now, fold the top right across so that now the top of your box is folded at the same place where your cuts are made. Tape where the folds meet the rest of the top. I then tape the top flap to the bottom of the box sides so that you end up with a "roof" like structure with the top not going all the way across the top of the box. If additional support is needed to insure the new box "roof" stays put and does not wobble, I often tape Popsicle sticks to the inside of the box going across where the side and the new "roof" top meet.
Next, use clear wrap film that comes in a roll ( and cut a piece big enough to be adhered to the top box "roof" and then come down across the opening to be adhered to the front of the box. Only tape the top of the clear wrap and fold it back until you have inserted your cake. Once your cake is inserted, then drop it down and tape it into place and neatly fold back the sides like you are wrapping a package and tape it into place. I then put my bakery logo on the top of the roof and another one on the very front bottom of the box. Sometimes I even add a bow to the top of the box.
The neat thing about this presentation is it is entirely professional looking, is nice and neat, and gives a view window into the creation. The view window works perfectly for delivery especially if the cake is being further transported by the customer. The customer can see the creation and yet it is protected from dirt, dust, rain, etc. I even delivered a cake boxed like this in a sleet/ice pellet pelting back in February with no ill effects at all to the cake.
