I had to change the seals recently in by GROHE PRESSURE BALANCE VALVE CARTRIDGE TIIEF value. Unfortunately, when trying to remove the handle after loosening the setscrew, this handle was still stuck. I finally got it off, but this piece broke in the process. I spent a bit of time looking for this online, to no avail.
I hope this saves someone in the same situation.
Happy printing.
