Here is a quick snap of my progress (part of it) today.
Both fan and laser are in the Cat6 connected cable.
On the back end of that I use a molex (since its heavier gauge than the normal wire, i dont think im at much risk of heat etc).
I wanted to be able to remove mostly any component or run of cable to trubleshoot or when i have to move the machine (mine is 40×40)
I may change out the molex for the D660 , ill just see how that goes.
