Introduzione
Nozzles on a 3D printer are considered consumable items, meaning they are commonly replaced during a 3D printer's lifespan. The more you print the quicker the nozzle will wear out.
Reasons to replace a nozzle include:
- Desired nozzle diameter
 - Clogged nozzle
 - Nozzle deterioration
 - First layer failure
 - Print speed
 
This guide will demonstrate how to replace a 3D printer nozzle for the Creality CR 10s Pro V2.

Using a 2 mm hex key, remove the two screws that secure the fan cover.
 - 
            
Position the fan cover in a way that doesn't damage the external wires.

Once the nozzle is sufficiently heated, use an adjustable crescent wrench to firmly hold the heater block.

With the other hand, use the tappit wrench to unscrew the nozzle.

Once the heater block is cooled down, slightly thread the new nozzle onto the heater block.
 - 
            
Manually set the nozzle pre-heat to 230C and finish threading the new nozzle.

To ensure the nozzle replacement has been followed correctly, calibrate your 3D printer.
