Mitutoyo micrometer battery cover and wrench

I redesigned the 2pc model into a single part and made the head thicker to allow more solid fill layers to ensure that there are no gaps in the model that could let coolant into the battery compartment. I also added 4 driving lugs to help prevent striping of the slot along with a wrench to match to loosen the caps easier. So far so good I will update if I need to make any changes after some use in the field. I included STEP files so you can tweek it your application if needed.
