Update: November 27, 2021 – I noticed that parts with tiny warped ends would scratch my mount, so I raised it up 0.6mm.
I made some small tweaks to allow this to work with the Zodiac hotend. By proxy this should also work with the Phaetus Dragonfly hotend, since the Zodiac is a direct variant of that.
Because the Zodiac hotend sits lower than the stock one from E3D, I lowered the mounts another 2mm so that the fans were not just blowing on the heat block.
I also realigned the upper and lower right mounting holes that screw into the extruder. When I imported the original stl and lined it up with the extruder part they seemed slightly askew. Functionally I don't think it is much of an issue as it is a very small skew, but I thought I might as well account for it in my remix.
WARNING: This will NOT work with the stock E3D hotend, as it sits lower than the nozzle and would crash into the bed. For a dual fan mount that works with the stock hotend, go here.
