I use the NextG Fiber plus melt-zone extender hotend but the A4T configurator only had Dragon + MZE as the closest option available so I needed to personalize my own hotend fan duct.
I kept getting heat creep whenever my chamber exceeded 50°C while printing ABS until I finally noticed the configurator provided STL file was not optimized for my heatsink.
While I was in there designing I also added stator vanes so the exhaust air did not crash into the X-linear-rail, but instead had a guide to less resistance down and out through the XOL carriage.
