Lightweight Cooler 2 Piece Modular remix

This remix splits the shroud and duct into two parts. This way you don't need to remove the PTFE tube to install the shroud. In addition I think maintenance is easier, since it is easy to take off the fan screws and move both the hotend fan and the part cooling fan out of the way for easy access to the hotend.

The duct part of this design may be somewhat difficult to print. You should figure out the best orientation for it yourself; I think I did something like the included picture using a raft and aligning the end of the part cooling fan hole with the build plate.
