Where does the 3rd fan go?
I bought this preassembled but then the print head came off the rails (not to mention the fan in the back falling off) but never took a picture of the completely built print head. Now when I have it reassembled I cannot figure out where the third fan goes (see the attached image). I have the build instructions but I don't see where it is mentioned in there. I have the front fan under the gear drive and the rear fan that connects to the assembly that goes around the nozzle. Where does the third fan go?
RE:
By my count that's the second fan on the toolhead (there only are two). It goes right onto the heatsink which it is dangling next to, mounted via the two screws on the left: https://help.prusa3d.com/guide/6-nextruder-assembly_849034#850040
Edit: Probably you were confusing the heatsink (which is already installed) with a fan. That's not what it is; it is just a piece of black-anodized aluminum with some milled-out slots.

Thanks. Now onto the next issue! 🙂
