So wife’s iPhone 6 battery died. I am working on replacing it and and saw the tooling marks on the inside on the aluminun case back. I would love to see that cnc in action to make the case. The mill looks to be no bigger than 3/8 ” diameter. I am so use to injected molded parts and never thought what it takes to make this finely crafted design. #TheGarageEngineer #ABC #AlwaysBeCutting
