Lift up the hot end mounting plate a bit and press
the PEEK shroud into it's fully installed position.

Note how the power wire passes to the outside of
the fan shroud body. Also make sure that the power
wires for the fan are not pinched between the hot
end mount and the fan shroud. They should be
resting in the notch.
Wire the fan into the PEEK fan wires by either
using JST connectors like I've done, or just splice
them together and cover the splice with a fold of
Kapton tape.
