This is a magnetic fan adapter, support bracket, and optional inline booster fan designed to help vent 3D printing fumes from the Creality K2 Pro. The system interfaces with standard 2-inch built-in vacuum piping, which is inexpensive, lightweight, and readily available at most big box hardware stores. The fan adapter mounts magnetically to the printer to allow quick disconnection and easy movement of the machine when needed.

An inline booster fan is optional. The printer will still vent using its built-in fans, but those fans shut off after the print completes. I added an inline fan to my setup so ventilation continues even after the printer finishes.

Support Bracket Versions:

There are two versions of the support bracket;

A) 2mm hole version – holes pre-sized for screws

B) Self-drill version – designed to be drilled during installation

I used the self-drill version for my build, but included the 2mm hole version for users who prefer not to drill.
