This is a three-part system for venting your K40 laser to a 3". hose. All parts are removable externally for easy access and maintenance.

Once you remove the old intrusive internal exhaust you can insert the new shorter one, followed by the gasket which should snap on pretty firmly to the internal exhaust. Then simply slide the outer exhaust in behind it for what should be a snug fit.

If you don't feel like wrestling the inner exhaust out (you have to remove the X/Y table) then its recommended that you either replace the screws with something countersunk so they sit more flush or use the gasket as a template for a piece of EVA craft foam that will form around the screw heads.

NOTE: supports are ONLY needed on the outer exhaust and only for the small overhang on the 3" port. You can adjust your support overhang settings until only that portion is left.
