I managed to download all versions from gdrive before the gdrive links died.
I uploaded it here: https://files.catbox.moe/aefqa4.zip (if the page doesn’t work, you need to change your DNS)
I think kde planned to release a wallpaper pack anyway though, in which those would surely be included
Edit: I just realised they’re not all versions. Those that I named v1 are these and those I named final are these
