Got the plating and anodising done, also milled out the inside more and made a cradle for the sx350 and usb pcb. Will get the electronics in tomorrow and it'll be done, will post some better pics tomorrow but here's one with my phone (without a flash lol)
I have silver plated all contacts inside and also changed the default wiring on the sx350 with silver plated copper wire, teflon coated.
