Where to get EMC/EMI Metalic PCB Shield?
Eka:
Any technique they use for metal jewelry box making can be used to make custom metal boxes. A forming anvil could be as crude as a piece of tool steel bar stock cut off square and held in a vice. Dremels with cutoff wheels are great for cutting the shapes for tabs, etc into a sheet of very thin metal. A small precision vice can be used to clamp a piece of metal as one hammers over a small tab. Often with very thin metals, they can be formed with just hand pressure instead of hammering. I've used various rods and bars to pinpoint the pressure. For thicker metals various rods and bars can precisely direct the energy from a hammer blow.

Hello,
nearly every PCB manufacturer (at least here in germany) can etch your
housings from either brass or nickel silver sheets (0.1 - 0.3 mm thick)
I etched some parts at home with one of those photosensitive brass sheets:

On the picture: a housing, a coin cell holder, a holder for a o-ring gasket, and a spring which connects the housing to the front pcb.
with best regards
