This is one integrated mount for E3D V6 hot end for ultimaker original. Designed to be used with ultimaker heater cartridge but with e3d heater block.  You can use even a thermistor or thermocouple (it have holes for thermocouple transmiter)   For use the thermocouple you have to take out the thermocouple from its original encaspulate (metal) and use it without it. (maybe you have to take out also the ceramic protection inside it) It's really easy to do.   With this mount you just need:  -Metal parts from e3d v6 bowden  -100k ntc thermistor with cables (if you don't want to unmount your thermocouple)   -30mm fan  -2x 40mm fans (optional if you want symmetrical cooling)  Even it's designed to be in same place than original hot end you must readjust the XY endstops or change the trigger in the XY blocks (alan89 blocks are perfect for this)  Tested with Reptar XY blocks and the ones designed by alan89 (I use this ones). Not tested with original ones.      Double fanduct for 40mm fans. The fans are 4mm high to avoid clips for heated bed.  This is the first version, still testing it.[EDIT] Updated file for right fan, the one in E3dV6 was ok but the "right fan" file was an older version. Sorry.
