Hello everyone! I made a new fan duct for my prusa mendel i3 Rework and I was thinking why not share it with others! My original duct was not concentrating the air on all the sides of the hot end so I created a new one which does this way better. I also added the solidworks part for you to customize it in every way you like, but give me a message if you created something nice. It can be printed without support! EDIT: It's for a 40x40mm fan :) I just printed the part with a 0.3mm layer height and a speed of 20mm/s.
