Stealthmax Optional Extensions for Future Releases Airflow pipe to outside world + Inlet Airflow control

[hillerpa]

I created a Air Exhaust alternative to put it to outside Pipe - CAP is required for ABS printing
As well as a Air inlet to have a better control over the 40/60 Airflow ratio: Air Inlet

not very pretty due to I'm really a CAD noob but trying to get more advanced ;)

Thanks for your work!
