I'm not sure if this really answers the question... it doesn't seem to do so. However, it is related and interesting, and might serve better as two [sticky] comments (it won't fit in one).

<p>I am looking for information on the smart extruder+ heat block and nozzle?  I have looked online and from several forums come to the conclusion it is either a MK10 or MK11 assembly.  Can anyone shed some details on the heat block and nozzles.  </p>

This is probably their own design, not a MK10 or MK11. The heat block seems to have a coned extension leading up to the nozzle. Like Ultimaker, a crappy decision (I know as I have an UM3E) to sell those all in one (expensive!) cores (from the point of view from a tinkerer).

Thanks Oscar, being new to 3D printing this helped a bunch knowing I wasn't missing something or just didn't have the right search terms to the find the part.  As an engineer and tinkerer myself I just assumed they would make replacement parts or aftermarket parts like in most industries.  I am glad the replicator+ I got was free and it's a pretty decent machine.  I refuse to send the extruder back to MB every time I get a clog so I am going to buy a replacement and then modify the existing one.  When I purchase my next printer I will research how easy they are to modify!!! Thanks again

Maybe [this answer](/a/5437/5740) is of use to you, it shows history up to MK 11
