Here are the parts you need to install the Chimera or Cyclops hotend from E3D into the original effector.
This is a direct replacement.
Also included is the shroud for the part cooling fan and a laser cut bracket. I would suggest you do not print the bracket in plastic, but have it laser cut. If there is any flex in this, it WILL hit your printed part and rip something.
To get the shroud really smooth and light, print it via Shapeways.
