This part should allow to fit the new MK3 Fannozzle to an existing MK2(S) Printer.
You just need to swap the cover
the extruder-cover-MK2-MK3 is for an unmodified MK2(S) extruder
extruder-cover-cut-MK3 and extruder-cover-cut-moved-MK3 are for a clone extruder with a 1mm moved extruder ( https://www.thingiverse.com/thing:2261050 )

16.12 2AM: fixed a small missalignment, the nozlleposition of the part for the unmodified MK2 and the moved part is now exactly identical to the MK3
They seem to fit nicely, although i havent installed them yet
