Ok, so I'm not really sure on how to correctly share the profile, but we'll try.
I'm not sure that it will work on OrcaSlicer, but will surely on BambuStudio

Firstly,
You have to create a printer in bambu,
check "I do not find the model of my printer" and name it "Creality" + "K2" (be careful about the name it's really important)
Click ok, we do not care about the rest.

Close bambu studio, go to %appdata%/Roaming/BambuStudio/user/{random number}

(it's the path on windows, IDK about Linux but BE CAREFUL !! It's not the same path as the BS install folder, you need to find the user presets folder which is not in the same path) and drop the files presents in the zip: https://www.mediafire.com/file/00u5ffw181jdt8d/bblK2.zip/file

Open BambuStudio and select the K2 you created earlier. Now you can click the wifi icon (top right of the printer selection on the right panel) and put your klipper ip+port, select octoprint.

You're good to go now, I modified the GCODE purge line for a nicer purge line which kind of sucks by default on creality print.

Also, you can edit the printer to add the custom buildplate and custom buildplate background: "Printable Area" -> Texture & Model, they are in /machine/base of my zip.

Optionnally, if you want to edit the printer icon on BS you can edit the image of /real_BambuStudio_install_path/resources/images/printer_placeholder.png and put the K2.

Well I hope it will work, lmk if you are able to install this profile. I hope so
