Fairphone

Hello everybody! I'm looking for a sturdy and robust case, but I can't seem to find anything. I know that there is the good ol' official Fairphone Soft case, but I absolutely hate it. My phone often slips out of it when laying on the screen, and it feels like it doesn't even protect the phone. I know that I could just replace the screen if it were broken, but in the long term, a case would be more effective.

Is there any case around that is like This or a little less extreme like this?

Thanks in advance!
