Oil Cap Wrench

This is a tool specifically created for replacing oil filters on select Mercedes vehicles and potentially others. It perfectly fits onto a 14-sided cap that measures 74 mm in diameter. A friend who requested this tool has successfully utilized it and found it to be very effective. The design of the tool was intended to work seamlessly with a standard 32 mm socket, although users can easily modify this dimension by altering the "major_r_socket" constant within the OpenSCAD script if needed. Alternatively, an adjustable wrench can also be used in place of the socket for added flexibility.
