Creality K1 Rear exhaust pipe connection 38mm

I've made a right angled exhaust pipe for the Creality K1 for use of a ID 38mm pipe for those wanting to vent their printer due to smells & VOC's

The stock fan isn't that powerful so 38mm is still fine for air flow to remove some smell & heat from the chamber.

Simply, remove 2 screws from the fan inside the printer, diagonally preferred, and use them on the back to install this attachment. 

I'm using it with THIS Venting slot to put in my window. 

38mm hose ca be from a hoover pipe or Pond Corrugated Flexible Hose (Amazon)

Pretty much it.
