This is an exhaust duct for interfacing with a 3" blower that replaces the stock fan that comes with the K40 laser cutter.

The exhaust is cut into two pieces due to size (though I have also included a single part version should you have a large enough printer to make it as one piece.

I made this to interface with this blower: https://www.amazon.com/gp/product/B001O0DE9E/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1

But other 3" blowers should also work fine with it.

I am currently printing this out and finished the first section. I was going to do it as a whole piece but did not want to leave my printer unattended. I did notice how ever that you would need a sleeve or small hose between the duct and the motor. I would only suggest opening the duct a to accommodate the blower eliminating that hose and having both bodies fit snug in one another.

That's a good idea, thanks for sharing!
