Replacement Nozzles - Suggestions please

I would still buy the cheap five packs if I was doing anything but abrasive filaments. For the cost of a hardened nozzle you could buy a few multi-packs and replace the nozzle every month. Brass is brass is brass, so don't be fooled by the sourced from China expensive nozzles vs the sourced from China cheap nozzles.

Now also don't make the mistake of buying stainless steel nozzles. They are completely unnecessary and just buring money. They are built specifically for one reason, to eliminate any lead transfer from nozzle to finished print and are specific to the food and medical industries. The heat unevenly and are not much harder and will wear as fast as the brass ones will.

Hardened steel on the other hand is specifically made with abrasive filaments in mind and will wear nearly forever with normal filaments and somewhat shorter with abrasive filaments.

The reason I still use brass v. hardened steel all the time. I don't like cleaning out filament jams, although I haven't had one in a while. If I have a jam, I just remove the cheap brass nozzle and throw it away then put on a new pre-seasoned one. No muss, no fuss.

 

I have never seen variety packs, although you might be able to do something like that on eBay or Aliexpress with an email to the seller. I have been surprised that there aren't any variety packs available. I would certainly buy one or two then maybe five packs of the two most common sizes, that would give you a dozen of the most common sizes and two each of the rest. I have also thought hard about Hardened Steel (excuse the pun) and since I don't really buy abrasive filament in large rolls I can sacrifice a brass nozzle or two for the limited printing I do.

 

@Rigmarol Don't, the MK8 nozzles don't fit anything but Makerbots and Makerbot compatibles.

The threads on the Hexagon and E3D require an M6 nozzle like these https://www.amazon.com/CycleMore-Ex...6?s=industrial&ie=UTF8&qid=1471223485&sr=1-16
BTW, that was the first link so I will not vouch for it, it was just used for illustration purposes.

 

Speaking of Variety packs, look at this:

I know what I am ordering tomorrow.

And the following link is for @mark tomlinson to use with his Volcano

Any that fits the E3D should be fine. Whatever sizes (like 0.4) you want are up to you.
If you go a lot larger you will sacrifice speed since you will be forced to slow down (unless you install a volcano adapter).

 

If you are going to do more than occasional use of the CF embedded filaments you will want to use the hardened steel nozzles.

I went a year with normal PLA and no detectable wear on the brass nozzle. Other specialty ones (like woodfil, brassfil, stell, concrete, etc) will also cause faster wear. Now I just use the hardened steel nozzles all the time. Make sure you get hardened steel, not stainless. Stainless is harder than brass, but you really want the hardened steel ones.

The ones you link to are not the hardened steel.

 

These are the hardened ones:
