Diesel Filter Cup Wrench

This Is my first try designing on Fusion 360, I needed this tool to remove safely the filter cap from my volvo, I used an image from the tool and some information about the dimension provided by the manufacturer, still, a work in progress but I think that could work, I changed the design of the picture to fit a 1/2 ratchet wrench.

INFO: as the FDM printers maybe are unable to give enough strength, is better if you try to print this part with vertical layers instead of horizontal or even better if you try to make a mold and use resin or any kind of metal
