Quoted from Nepi23:That's a nice find PT! But if I wanted e.g. black mirror side blades to be made, what is the material I would be after? And just asking them to cut it in accordance with the design files?
Ask for chemically coloured black mirror finished stainless steel sheets in 0.8mm thickness.
As swinks mentioned in his post earlier, if you have the CAD files it will make the process much easier.
