With the E3D Revo CR upgrade kit you can change the nozzle without tools. The improved heatsink also ensures that printing can be done with a maximum temperature of 300ᵒC. The set includes a 24V Revo CR hot end with four interchangeable 0.25mm, 0.4mm, 0.6mm and 0.8mm diameter nozzles.
The E3D Revo nozzles are equipped with their own heat break. This means that it is not necessary to tighten the nozzle at a high temperature. Because each Revo nozzle diameter has its own colour, you can quickly see which nozzle diameter you have in the hot end.
