With the Nextruder, you have two ways to change the nozzle - you can replace the entire hotend or just switch out the nozzle without removing the whole assembly.

However, changing just the nozzle involves some risk. You need to grip the heater block firmly as you unscrew the nozzle. If you put too much pressure on the nozzle that's still partially connected to the heat break, you might bend the nozzle tube. Also, the heater just hanging on the wires once the nozzle is removed is far from ideal.

This accessory secures the Nextruder's heater block firmly in place. It allows for rapid nozzle changes with minimal risk of bending the nozzle tube. The development of this accessory was inspired by IBNobody's Nozzle Change Heater Block Clamp.

The parts are divided into folders based on the printer configurations.
