Ender 3 v2 neo Bell Inlet Duct

It's 5g lighter than the neo oem shroud, it might make the fan more efficient, it might be a little quieter (due to efficiency), it definitely looks cooler!

There is a left and a right version to suit fans with wiring on the left or right (if you look in the photo you can see the the original I printed was a “right” version which suited the oem fan, but one of the replacements from aliexpress have the wires on the left, so I do need to print a new one in “left” orientation.)

The one pictured is printed in PETG as it's quite close to the silicone sock on the hotend. Some clearance could be added possibly as it has melted a bit over time, but I just sanded it back and it seems fine.

Also worth noting is that the fan direction should be onto the heatsink, ie sucking in through the “inlet” (the clue is in the name) duct. (ask me how many times I out it back as a blower…) You need to check this any time you replace your fan.

Suggestions for improvements, or requests for any customisation are welcome, just post a make and let me know in a comment.
