Hardened Steel Nozzle with Finned Cooling Body for 3D Printer Hotend

This machine part is a hardened steel nozzle combined into a 3D printer filament feeder head, combining the nozzle assembly with a black finned cooling fin body, a dark gray lower housing, and an upper metal plate. The result is a compact hotend nozzle unit with a clear mechanical look and a 48 mm overall height. As a 3D printer nozzle, it functions as a central point in the printing path, helping guide material through the hotend assembly in a single combined form. The finned cooling fin body and upper metal plate add to the structured construction, making the part visually defined and easy to identify within a filament feeder setup. For users replacing or assembling a hotend, this format keeps the nozzle section and surrounding body closely connected for a clean install profile. The hardened steel nozzle material is a prominent feature, giving the part industrial character. In everyday use, this kind of filament feeder head is suited to printer setups where a compact nozzle assembly is needed and where the visible 48 mm height is important for fitting and alignment inside the machine. It is a practical choice when the goal is a straightforward hotend nozzle replacement with a solid, metal appearance.
