Abstract:
1. A printing device component comprising: a base surface; and a plurality of ribs extending away from the base surface, each rib comprising: a nominal guiding surface; one or more primary transition surfaces; one or more secondary transition surfaces; one or more angled surfaces; each primary transition surface beginning at the nominal guiding surface and ending at a secondary transition surface; each secondary transition surface beginning at a primary transition surface and ending at an angled surface; and each angled surface beginning at a secondary transition surface and ending at the base surface; the one or more primary transition surfaces comprise up to four primary transition surfaces, each primary transition surface extending in a different direction from said nominal guiding surface; the one or more secondary transition surfaces comprise up to four secondary transition surfaces, each secondary transition surface extending from a corresponding one of said primary transition surface; and the one or more angled surfaces comprise up to four angled surfaces, each angled surface extending from a corresponding one of said secondary transition surface.
