Tool to unlock water filter

Hello

I regularly need to unscrew a water block to be able to change the filter inside. Getting old, the task has become more and more difficult to perform with bare hands.

As the tool is no more on sale, I needed to create it. I initially wanted to carve it from wood and started to discuss over lunch with my best handicraftsman about the best way to proceed.

He then suggested unanimously with other people around the table that I should try the 3D Printing idea. Great !

I started to draft the plastic key on CATIA and got in touch with the 3D fablab. A short time later, I could get the part.

Now is time to try it over the week-end.

Thanks !
