Simplified and modified Oil filter tool.

First off, I want to say thanks for creating this tool. It was one of the best ones I came across and was the best starting point for what I wanted. That being said, I made some changes to suit my needs/wants. I removed the area that covers the flanges. I did this for a couple of reasons. Those flanges aren't meant for high torque application. If this tool cracks and slips off the filter housing, it will hit those flanges, and chances are it will snap off those flanges. This also shortens the part, which will save material and time. I removed the Toyota logo. This adds unnecessary complexity and would make the part harder to clean off support material. Last thing, I added size identifier text on top.
