surround fun duct

thingiverse

I modified the part created by Lugnut_91 to address the issue of thermal runaway. The original design was causing excessive heat buildup, so I redesigned the duct to reduce the amount of hot air flowing back towards the hotend. To achieve this, I shortened the duct along the Z-axis by approximately 1/10 mm. If you have any questions or concerns about this modification, feel free to ask!
