( Left connector: Original E3D [100k Creality Sprite]; Right Connector: ZH1.5 2pin )
Just change connector case to ZH1.5 2pin directly. No need re-crimp.


4) Send to https://www.pcbway.com or your local CNC service to fabricate the Hotend Heatsink | 1pcs
    - Material: Aluminium 6061
 
For ordering with PCBWay, you may need to provide Technical Drawing file.

Then submit for price quote. Wait for updated price within 1day ~3days.
(Price & shipping may not be the same as mine, due to different country & tariff issue.) 

5) Print the ECC-E3DRevo-Hotend-FanDuct v1 | 1pcs
     ## Print Setting ##
     - Perimeter: 2
     - Top/Bottom Layer: 3
     - Infill: 25%
     - Filament: PETG/ABS/ASA
 

======================================================================
For v1 (Whoever downloaded the early untested version 1, you may follow this steps.)

After received the parcel, i test screw the revo nozzle but not able to fit all in. I apologize for my mistake. I had edited the drawings n updated the files. 
You may need to modify by using 3.1mm drill bit to drill 19.4mm depth & M4x0.7mm thread HSS Hand Tap to 14mm thread depth. 
Here's my drill bit stopper:
https://www.printables.com/model/1316519-drill-bit-stopper-3mm
https://www.printables.com/model/1316543-drill-bit-stopper-4mm

Tested the HeaterCore to heat up to 250C & no error occur. But nozzle is hitting the Silicon brush's plate. Need surface milling and EDM process for v1 by 1.10mm. After the CNC modification, need to re-drill and and re-tap again.

 
The drawings had just been updated. Please download the latest drawings to avoid nozzle hitting the silicon brush plate.
======================================================================
v1.2.1
I updated the step file drawing with much precise of E3D Revo Nozzle.

PID Tuning Successful






With E3D Revo Nozzle, stringing issue is much lesser than the original hotend with same slicer settings. The print is much cleaner than original. It's quite easy swap the Revo Nozzle after unload the filament & wait the temperature drop till 50°C and below, dismantle by using your 2 fingers (No Tools needed) to grab it & unscrew then change to another Revo Nozzle. 
OEM Revo Nozzle found in AliExpress/Amazon also compatible.

__________________________________________________________
*** Take Notes ***
After setup everything, please do PID Tuning before print.  When you start test printing any object, if your nozzle temperature start dropping during the printing when airflow (Model Fan & Auxiliary Fan starts running), example: 255C drop to 240C & below. ErrorCode 103/104/105/106 will occur. That could be the Print Head PCB undervoltage issue. 

I recommend you to change your orcaslicer's cooling settings to reduce the cooling fan loads that affect your nozzle temperature:
Part cooling fan
Min:30% ; Layer Time: 1s 
Max 60% ; Layer Time: 1s 

Overhang activation: 10% 
Overhang & external bridges: 50% 
Exhaust fan during print: 30%~50%

With this cooling settings, i tested. Printing while airflow started running, nozzle temp drop from 255C > 251C. Then nozzle temperature stays within 253 ~ 255 (not dropping so much). 
It's stable and didn't occur any error.
