air assist and extractor v2 for neje

air assist and extractor for neje 2s plus 30 watt laser. 

uses cpap hose for extractor and air tube for air assist. 

you will need to cut off the steel tubing to the length you need. it needs to be inserted into place in the model so that it dont melt.

i made a adaptor to connect the vacuum hose to the cpcp hose.

it is sized to my focus of about 23mm +-.

minimal supports needed.
