With this part you will have the BLtouch close to the nozzle on the Anet A6.

The BLTouch is placed in the position of the blower, and the blower is moved to a different place. This way you won't lose any print space (the size of the carriage on the X axis is kept the same).

I'll upload the fanduct for the blower also (File named: "Nozzle Cooler").
You can use a small 3mm screw and nut to grip the fanduct harder witht he blower.

The distance between the BLTouch tip and the nozzle are the following:
X: 30mm
Y: 0mm
Z: Adjustable, you'll have to calibrate yourself.
