Description
This is UNFINISHED but it should work as I've printed and test fitted it a bunch of times to dial everything in while designing but I have not actually printed with this on my enderXY.
Unfortunately I'm abandoning this project as I've decided to go with a different extruder/hotend on my printer.
The duct is based on the Pudgy duct, I mirrored the ducts and redid some parts of it to suit this setup better.

Hardware:
(Going from memory, sizes could be +/- a size, I wouldn't try and force any screw that appears to be binding)
----------------------------------
M3x10 SHCS qty: 1 (Mount to H2 V2S)
M3x8 SHCS qty: 12 (8x X Carriage assembly, 2x Top/Bottom Mount to H2 V2S, 2x Microprobe mount)
M3x20 SHCS qty: 3 (2x Fans to duct, 1x duct to hotend fan to H2 V2S)
M3x5 SHCS qty: 2 (X endstop PCB to X Carriage assembly)
M3x5x4 Heatset qty: 6 (4x X Carriage assembly, 2x duct)
The belts run between the MGN12 and the X Carriage assembly then loop back behind the H2 V2S, the EnderXY included back plate is NOT needed (idea taken from the Voron family of printers). The lower belt has a cover plate since that belt is below where the H2 V2S contacts, it also has some slots for zipties to secure the heater and thermistor wires.
There are more holes/slots along the side and the back of the assembly you can use to secure wiring with zip ties. If using the Biqu Micro Probe there is a slot on the backside of the center of the duct to allow the wires to pass behind and then under the stepper motor then it can join the main wire bundle around and up to the top of the assembly.
The X endstop PCB is now on the extruder assembly and used a trigger plate on the left MGN12, the Y endstop has been relocated to the rear to aid in wiring and theres a front rail stop to replace where the original Y endstop was located.
I don't have great pictures of the assembly but have included the few I did have as well as different views from fusion 360, I've also provided a .step file with everything assembled.
The STLs are NOT orientated properly for printing, I just quickly exported this since a few people on reddit were asking. If theres anything seriously wrong let me know and I'll try and make changes and update this but I'm no longer investing any serious time into this project.
The duct requires supports (I used tree supports), I've included a screenshot from Orcaslicer showing the orientations that were successful for printing.
