I got annoyed at how the extension fit on my oil filter cap wrench, it would extend too far into the hole and it would fall off easily. So grounded the end down, drilled and tapped the tip and screwed it onto the cap wrench. Then cut grooves into the end so I can grip it easy with my fingers even when oily. I had to grind the screw head down a little so it cleared the bottom of the oil filter when in use.
