Biggest Trading card box. Barely fits the bed!

On FilamentWizards design noticed a screenshot of a trading card storage box that is 3 of the regular boxes combined, however when i downloaded the file it doesnt fit the Bambulab build bed at all. 
I redesigned it, combining it with all my tweaks that i applied to the regular boxes and i made it fit the bed, Barely!

Please note that printing a object that is as big as this comes with warping challanges!
Even if your layer adhesion is great the print will yust pull up the corners of the magnetic build plate !

The print profile i uploaded has reduced cooling to reduce this effect. but it might be needed to tape the magnetic build plate to the machine.
