I liked the idea so much that I started to develop my own version while drzymala did not finish his. Congratulations and thank you very much to the author.

NOTE: This venting duct is dependent on the height of the hotend. If your hotend is of different height then you need to edit the bracket at the top as well as the height of the holes in the back.

Print with your back down (in the position where the model is distributed).
