XXX (3) Fans Print Head For Anycubic Kobra 2 series (UPDATE)

      New Revision Release !  

           For reduced support (New place surface on bed )  and  increase the fan mounting strength when the print head is operating at high speed & add T10 LED slot.

 XXX (3)  Fans Project

      The custom print head is designed to replace the existing print head due to  existing heat sink cooling fan is small (Model 3010  ) and couldn't visible from the front side.  ( It may help extend the lifespan in case the PTFE tube is clogged. (My opinion)

     Also would like to reduces noise from the nozzle head cooling fan (existing Model 5020) by instead  with  Model 5015 fan 2 units.

    **** Cancelled old models due to have New Revision ****

              Seizing & Material Requirement

   Model can attached to extruder 2 case  as

             CASE 1 : Attached to the extruder 2 points as shown. 

     The original bolt is M3 x 30mm, which needs to be changed to M3 x 40mm.  ( 2 sets)           

Case 2 :   Attached to the extruder  4 points as shown.

    Hotend Heat sink    existing nut as M3x20 mm. , which needs to be changed to M3 x 30mm.  ( 2 sets)           

                 All Model use  5015 Fan      

         Fan nuts use M3 x 20  with nut total 3 set  

               2 Fans ( Left & Right have to connected by solder before connected to cooling fan terminal.

       Location of Fans

          1.  To install Fans at Left & Right (Nozzle Cooling Fans (instead Model 5020))

          2. To Install CenterFan ( Heat Sink Fan (instead Model 3010 , Existing Fan shall be disasssambled))

      Some parameter for print setting

         Lay Out on print bed as,

                            For  model LED ,  desigend slot for  T10  and 5 mm. LED bulb  https://www.make-it.ca/5mm-led-specifications/

     Case 1.:     Use 5 mm.  LED, shall be connected with resistor and connect to heat sink fan or cooling fan (de nd on your) , You can see at https://ledcalculator.net/#p=24&v=3.2&c=20&n=2&o=w  

                  2 LED series with 1 resistor  as. 

 Use 1000 OHM 

    Case 2 :   use 12V LED bulb (T10  plastic bulb) like as 

take out plastic bulb and series 2 bulb by solder and tap to Heat sink/Cooling terminal wire  . Beware some type that high power LED bulb will more hot and more load of your Fan driver circuit. 

               Have fun ! 

  NOTICE : 

        Be careful when connecting the wire / Connector  .
