J-Head (new design) with 0.25 mm nozzle for 3mm filament

This kit contains all parts which are needed for the assembly of J-Head hotend MK IV-B as described on reprap.org/wiki/J_Head_Nozzle. This Hotend is intended for 3 mm filament.

ATTENION only intended for PLA. For ABS and other hightemperature materials we recommend this hotend. 

Improved version:

  • with a readymade heating element instead of the simple resistor.
  • grub screw for clamping the heating element.
  • special hole for the thermistor.
  • No firecement is needed for build up, only a piece of kapton tape to fixate the NTC.

 More information about this hotend can be found in our wiki.

The following parts are included in the set:


* 1x 100k thermistor type NTC 104GT-2, Beta = 4267
* 1x heating element
* 1x 4 cm thermostable isolation material
* 2x small ferrules
* 1x carriage
* 1x 0.25 mm nozzle
* 1x carriage for power resistor and thermistor
* 1x PTFE tube
* 1x PEEK heatsink
