Best way to shorten hot end assembly by 1mm?

[Titan]

So you just have to adjust the machine to fix the problem? cool.

Yeah, bit of a bodge to be fair. It turned out the easiest fix (by far) was to forcibly push the part cooling fan, which has the bed level sensor attached to it, down closer to the bed. The part cooling fan is just held into place within the hot end assembly body by friction (no screws or anything!). It's held in surprisingly tight, so I just carefully pushed it downward by 1mm to compensate for the extra 1mm length of the nozzle.Hopefully the basic diagram of the MP10 hot and assembly I threw together and the attached photo helps better explain. :-)I highlighted the extra 1mm gap by circling it in red on the photo. Simple fix in the end.
