The stock part cooling fan and duct only cool the part from one side. This is my take on part cooling fan duct that directs air from three sides. I printed mine out of Prusament ASA. I print flat with tree supports

06/12/2023 Update: Reduced dead air space and added a third outlet to the center to add more cooling to the front face.

11/19/2022 Update There seems to be some variation in extruder builds so I have included a longer version if you feel the original does not line up depth-wise.

12/12/2022 Update: Based on feedback i have better centered the model and directed the air at the part better.
