A simple small sci-fi shipping container for 28mm wargaming. It's 41mm tall, 48mm wide, and 60mm long.
The part should print fine without supports. In doing so there will be a little sag on the top surface of the bottom row of side cutouts, but it's negligible and not visible on the tabletop.
Games Workshop Space Marine shown for scale purposes only.
Update 2017/07: Additional variants and a small collection of matching smaller containers and chests are now available on DriveThruRPG.
