If you make a mistake here or don't insert the NTC resistor properly in the whole your temperatures will be off and your prints will fail. You need a lot of patience here :) On the right is a picture of the whole hot end. It is actually up side down. Eventually the plastic flow from the little hole on top of the copper nozzle. This is the print head and it will be about 0,25 mm from the print bed. Another remark is in the manual that you need to tighten all of this very good to prevent leakage that will be unrepairable and will cost you a new hot end. So again. Patience and check and double check everything.
