Not likely. The materials from a 3D printer tend to be weak and inaccurate. I was thinking either injection molding, or CNC milling. I am leaning towards the latter. Either send the design to a place over seas, or there is at least one place here in the Bay Area. I'd love to do aluminum, and then treat it to color it.

Embed the little pieces of metal to hold to a touchstone behind or in the material. The closest to the surface, the best, and will give you the strongest grip.
If I can get a metal back printed like I want, I will probably be doing a similar process. Though, I'd like to cut out a piece in the back for the coil and use some durable rubbery plastic.
