Here's the files for the new fan duct and bracket to compensate for the silicone sock around the heater block. This should provide enough clearance without melting the fan duct while still providing enough airflow. Let me know if you guys have any suggestions for revisions.

Any special orientation to print these? I was able to get the duct to print good, but the bracket keeps crapping out on me. No idea why either. I have it printing flat with support and a raft. The bottom half prints fine, but as soon as it reaches the two areas that extend higher, it looks like it is under extruding and fails.

I am actually having issues with the duct. tried a couple different orientations but still not looking good. What filament are you using? I am printing with PETG (might be part of the problem for me). I will try some PLA next and see if I can get something nice.

I'm using PETG as well. The duct I did on the end where it connects to the fan. Up and down. Look at your existing one for layer lines. I have narrowed mine down to retraction issues still... Really not liking bowden so far. Direct drive was much easier to use.

Really not liking bowden so far. Direct drive was much easier to use. im thinking of converting mine to direct drive. i cant get rid of blobs no matter what. specially when im printing fast . i guess the fillament is acting like a spring and to much pressure builds into the hot end. to not modify a lot the hot end carriage im thinking to make a L braket to attach it on top and run a very little short tube to the hotend .
