New nozzle cooler 3d file


i didnt like the original nozzle cooler ( because it melted all the time) so I designed a new one. 

I will make another different one because I dont like the 1 sided cooling, it is not optimal for ninjaflex. the uncooled side will stay too hot and deform.

are you getting the HS to print with ninja flex?

I thought it would not work with the bowden extruders.


hi yes I can print a little with ninjaflex but it needs some transformations, also a 0,5mm nozzle and the result is not very clean or precise. and it is VERY slow. max 1000mm/min

you need to make a new part to connect the top bowden fitting to the extruder motor. means you need to remove the motor..(its quite simple)  I will post the plan of the part later. 

Here is my duo cooler nozzle. 

it cools the nozzles from left and right side simultaneously.

  • Requires heated bed.
  • Works reasonably well without cooling.
  • Adheres best to polyimide tape.
  • Filament tolerances are usually tighter.
  • Prone to cracking, delamination, and wraping.
  • More flexible.
  • Can be bonded using adhesives or solvents(Acetone or MEK).
  • Fumes are unpleasent in enclosed areas.
  • Oil Based.
  • Extrude at ~ 180-225o C.
  • Benefits from heated bed.
  • Benefits greatly from cooling while printing.
  • Adheres well to a variety of surfaces.
  • Finer feature detail possible on a well calibrated machine.
  • Prone to curling of corners and overhangs.
  • More brittle.
  • Can be bonded using adhesives.
  • More pleasant smell when extruded.
