This is a tool for changing the oil filter in certain Mercedes (and possibly other) vehicles. It fits on a 14-sided, 74 mm cap. I made this for a friend, who reports that it works well. The tool is designed to be used with a 32 mm socket. This can be changed by modifying the constant major_r_socket in the OpenSCAD script. Or, you can just use an adjustable wrench!
