Water filter wrench for removing and changing the water filters. Can tighten quite well without snapping or braking.

Insets are 2.4mm deep and 4mm wide at every 22.5 degrees. The inner ring is 70mm.

The story is that I bought another filter for someone and the seller forgot to sent a wrench. So measured out and designed ones.
