Abstract
An example print component includes a container interface with a guide feature to guide rotation and a rotationally asymmetric key feature. An example toner component includes a recess to receive a toner container, a guide feature to guide rotation of the toner container, and an asymmetric key feature embedded in the guide feature to guide a container material interface towards a component material interface upon rotation. An example container may have a periphery with a rotationally asymmetric surface plane to guide rotation of the container and a protrusion extending from the periphery that has a key feature defined by edges rotationally asymmetric with respect to the periphery. An example container may include a mechanical interface including an asymmetrically-located key feature that, upon rotation of the print material container, generates a sealing force substantially perpendicular to the direction of rotation.
