It’s a modification for the Ultimaker 2 / 2+ series of 3D printers that allows the extruder nozzle to be swapped within seconds, as opposed to replacing the entire heater block every time. This lets you pick your nozzle on-the-go to fit your particular needs.

This block will also serve as a replacement nozzle and heater block kit for the Ultimaker 2+ (as it is standard equipment on the 2+).
If you need large prototypes printed fast, the 0.8mm nozzle will let you extrude the most amount of plastic in the shortest amount of time. If instead your print requires high detail, the 0.25mm nozzle will let you print extremely small objects or give your normal prints an extremely smooth and detailed finish. The 0.4mm nozzle represents a balance between these two extremes.
