This is a lovely question mark box from nintendo. I redesigned the inside to fit 16 Switch game cartridges. More importantly, the stickers of all the 16 cartridges will be visiable all the time. You don't need to pull the cartridge out to find out which game it is.
You will need super glue to stick the white question marks on the lid. I know you have AMS, but I don't think it worth the print time. So I designed them as seperated and required glue.
Another extra item required is a rubber band maybe from your grocery shopping. The rubber will provide motion to the locking machanism so that the lid can be locked.
I have modified the bolt a little so this easy to open the locked lid.

Mine was broken the other due to a weak point on the lid. I made it bit stronger now. Hopefully it can last longer.
