Hi,
It looks quite simple, so it's just the dozen or so divider bosses you want to remove?
You can always print this and cut the bosses manually.
Otherwise Blender has a good boolean modifier that you can use to subtract a box shape from the master model.
That will be your homework
Keep us updated!
