brought next idea :
Replacing the cartridge in an early Aqualisa 200, but could not get the rear
o-ring out. Showerdoc is hopelessly optimistic when he says use a crochet
hook. Maybe the design changed a bit later, there's no way to get anything
behind it. The only option I can see is to skewer it, but my skewering items
all failed to get far into the rubbed, it's stiff stuff.

Any ideas to get this thing out? Ie what tool could I make?
