Ultimaker 3 and S5 PrintCore Nozzles (AA and BB)

https://github.com/Ultimaker/Ultimaker3

Not my design, Ultimaker's design from the above link, exported as STL in Fusion 360.

No threads on these models, this is mostly for demonstration of the nozzle internals. The threads are M6x0.75 if you're curious.

Edit: Uploaded a 0.4 BB core with the threads.
