Just a spare titan drive gear, exactly as shown. Both regular and hardened versions are available. The hardened steel hobbs are a drop-in replacement for the standard stainless steel hobb supplied with every Titan extruder.
Note that as of 9/2018, hardened hobbs no longer are black in color, the metal is silver, and looks similar to a standard hobb.
While hobbs and drive gears wear at a lower rate than nozzles with extensive use of abrasive materials like carbon fibre-filled filaments wear does become an issue. Hardened steel hobbs effectively eliminate wear even when printing with the most abrasive materials for extended periods.
