I designed this box to hold an NCE AIU board serving as a breaker reset box for my modular club layout. The lid is affixed to the body of the box using 4 1/2" #4 screws. The AIU board is held in with 4 #6 screws cut down to not protrude out the back (I believe they were #6, but I don't remember for certain).

Print the main box as it. If you print the lid with the raised text on it, you'll likely want to print it text-side up with supports. If you use one of the other lids, flip it over and print the lid top surface down.

(The strange color splotches in the photos are from spilling some isopropyl alcohol on the box)
