K40 outlet duct to 120m fan to 4 inch duct vertical adapter

thingiverse

This is an adapter for the rear exhaust of a K40 Laser Engraver. It allows for attachment of a 120mm fan, which then outputs to a 4 inch dryer hose. The difference between this and others is that it is vertical, which I needed due to space constraints. There are two versions of the duct - a one piece version which will need to be printed with supports, and a 2 piece version which you can print without supports, but will have to glue/melt together. I made mine out of PLA remnants, and put them together using a 3d printing pen.
