Happy Cetus3D owner

Ever since getting my replacement board I have been actively using, and learning, with my Cetus3D.  I have had filament breaks and stuck pieces but I was able to work through them. The quality of the prints is awesome. The only question I have now is where do we get replacement throats and nozzles?  I can't quite find the type of throat that is used on the printer. 

I'm not exactly sure what you mean by throat but if you're referring to the plastic? tube on top of the metal nozzle then the answer is it comes as one piece with the nozzle when ordered from Cetus.  

Looks ceramic to me. I knew it wasn't the nozzle. I just didn't know the name for it.
