Dual Cooling 40mm Fan Attachment for Kossel Mini

This is my first design using DesignSpark Mechanical - a free cad program that I recommend for beginners. It is a 40 mm fan attachment for Kossel Mini with J-Head Hot-end. I split the airflow in half, the top parts cools the PEEK of the hot-end and the bottom half flows in two channels around the tip of the hot-end and is directed at the printing nozzle.
The attachment also contains the attachment piece for the J-Head to the Kossel Mini effector and uses three 3mm screws.
