Answer

To remove the nozzle of the 3Doodler PRO you must have the pen turned on and heated to at least 180 degrees Celsius. Using the nozzle set holder (which has a nozzle removal tool built into it), unscrew the nozzle in a counterclockwise direction.

When replacing the nozzle, make sure the pen is at least 180 degrees Celsius and screw it back on with the nozzle set holder in a clockwise direction. Do not over-tighten the nozzle when replacing it. Stop tightening as soon as you feel resistance so as to avoid over-tightening and breaking off the threaded pen tip.
