Grohe - o-Ring holder - item 12701000

thingiverse

The shower started leaking, which led to a discovery. The "mixer" was the culprit. A crucial metal ring, designed like something inside a rocket booster, had cracked. It was part of the o-ring holders. The solution would cost 55 Euros, plus 4 weeks waiting time before it could be ordered. This news was quite frustrating. Fixing the problem required getting an ABS ring instead. Fortunately, one of these rings is readily available and very inexpensive. The estimated price is just half a Euro. What's more, it won't take any time to find one at all. In fact, I already have the part and can fix it in under 4 minutes.
