Fluid ejection device assemblies

A fluid ejection device assembly, comprising:

• a monolithically molded body comprising:
• a print fluid reservoir;
• and
• a monolithically molded fluidic structure sealingly attached to the separately molded body, the fluidic structure comprising:
• a plenum to receive the print fluid at a fluidic interface with the body, and to deliver the print fluid to a separate downstream fluid ejection device, and
• a headland against which to attach the fluid ejection device.

A monolithically molded body to couple to a separately molded fluidic structure attached to a fluid ejection device, the body comprising:

• a print fluid reservoir;
• a recess across a downstream bottom to support the separately molded fluidic structure;
• a standpipe between the reservoir and the recess, the standpipe opening into the recess to supply print fluid from the reservoir to the fluidic structure at a fluidic interface of the recess;
• and
• two protrusions across the bottom, with the recess in between, so that, when attached, the fluidic structure extends between the protrusions.
