UPDATE:
I made a remix where I added mounting holes for the stock fan and struts to the hexagon shaped cutouts (since people didn't add mosquitto net).
You can find the new version here: https://www.printables.com/model/783591-kobra-2-series-psu-coverlid-for-stock-fan-andor-no
This is a remix of the "Kobra Go PSU (Chengliang P400W24V) Hex Cover for Noctua 6025" for using it with the stock fan the PSU of the Anycubic Kobra Go/Neo comes with ("Cheng Liang CHA6024RL-15B", 400W, 24V) where I closed the cutout for the Noctua fan.
Due to the same PSU being used, this cover fits the PSU of the
- Kobra Go
- Kobra Neo
- Kobra 2
- Kobra 2 Neo
- Kobra 2 Pro
- Kobra 2 Plus
- Kobra 2 Max
No fan upgrade needed, just mount the stock fan!
It was a massive improvement on my Neos, the printers' PSU are much quieter now.
Thanks to @pepson_594770 for making that initial remix!
Mounting:
- You need to drill mounting holes or just use some shims and the screws of the original fan mount to clamp the fan to the cover like I did.
- I hot-glued a piece of mosquito net to the inside of this cover to avoid getting any small parts (or cat hairs..) into the PSU.
- I'd suggest to mount the fan in the direction that it blows into the PSU. In this case the 'scoops' of the blades should face the inside of the PSU.
Note: the four small mounting holes aren't mean to be used to mount the stock fan - they are from the original model I remixed and are meant to mount a 6025 Noctua fan. I left them in here so that one could easily cut out the belonging part of this lid and retrofit a 6025 later as in the original model without having to print the whole new lid for being able to do so.
Material & settings:
Just use whatever you have laying around - the one in the picture was printed with a rest of PETG and 0.2mm layer height.
It's advisable to slightly raise the printer by using e.g. longer feet or risers for the stock feet, as this cover sticks out a few milimeters more.
Due to the fact that the PSU is now almost ‘uncovered’ in terms of airflow-inhibiting structures, it might also work well without rising the whole printer though, especially when you don't use an enclosure for the printer.
I added a picture of the original metal cover laying next to this model, just for comparison how much of a difference this one is.
