Action shot from my heavily modded Ender-5 printer using this mount. I'm currently using https://www.thingiverse.com/thing:2323014 to mount a second 5015 blower to cool the Chimera.
Nice make, How do you reduce oozing? What filament and retraction settings, etc are you using? That looks awesome.
I'm using Simplify3D with the ooze shield turned on, which is the outer perimeter you see around flexy rex there. Simplify also adds a 12mm @ 10mm/s retraction when it's switching nozzles, that seems to do really well at minimizing oozing. For regular retraction, I'm running 3.5mm @ 60mm/s, 1500mm/s acceleration, 10mm/s jerk on the extruders. The filaments there are Hatchbox Orange and 3DSolutech gold PLA -- just whatever I had laying around.
