so the split files are 7z (001, 002, 003)
when you extract it, it gives a .zip file
-rw-r--r-- 1 root root 3222907835 Mar 7 16:14 kopiemtu-1.0.zip
this file is the exact same size as the one here: http://18.104.22.168/kopiemtu-1.0.zip
trying to extract this zip file:
└─[$]> unzip kopiemtu-1.0.zip
skipping: kopiemtu-1.0.img need PK compat. v4.5 (can do v2.1)
└─[$]> 7za x kopiemtu-1.0.zip

Is not extracting as zip or 7zip. I'll continue looking into this issue.
If you could just host the .img directly on dropbox or something that would be fantastic.
