This blueprint allows you to stick a large container to the ceiling using an update 7 blueprint.

I was doing this repeatedly using foundations shenanigans in order to create the illusion of it being stuck to the ceiling. Using blueprints you can stick it right to the spot on the ceiling where you want. Made even more useful by ceiling mounts for conveyors :)

Ceiling mounts align with the container openings, and there's enough room to run a belt across the top of it.
