Optional e3d V6

I am just about to order the seemingly wonderful smart effector but look as I might I can't seem to find the answer to one particular question. So, at the risk of asking something obvious and in so doing looking a bit stupid, is the optional e3d V6 for 1.75mm or 3mm filament? There, I've said it…......

I haven't heard anyone mention 3mm filament. It is just the heatsink that you are getting, so not sure that it would matter anyways.

the heatsink is included. You can optionally add the rest of the V6, which is what i did and the one i got is 1.75. I dont see any options for 3, so i think they are all 1.75. though i could be mistaken and it could be a possible option, i just know the one i got is 1.75.

Thank you muchly for the swift replies. That is essentially what I had assumed but nice to find out for sure.
