I have a Kinetico K5 drinking water system and changing the filter is not too tough, except for the very last one.  I cannot get my ham hands in the assembly far enough to get a decent grip on the front filter.  So, after I finally got it out, I printed a wrench that you can reach in from the hole inthe bottom and engage the bottom of the filter.  It is just a quarter turn, but when you only have wet finger tips “gripping” a smooth surface, it seems like 8 turns.  This wrench greatly simplifies things.  Print it with the handle up or down - you will need supports either way.  I printed it handle up to waste less material and made it out of PETG.  The inner support popped right out in one piece and the wrench fits perfect.
