Hey Brian, here’s how I did mine. I used my wife’s old plastic case, painted it black and did a 2 ply veneer of birds eye maple on the back held on with double stick tape. It has held up quite well for the past year.
That is spectacular. Nice work. I have a leather flip case but if I had a hard back case, I would definitely give that a try. But I think ca glue would do the trick more permanently. I abuse my phone more than my wood projects. LOL
Mostly looks like a thin veneer applied to a basic case, probably not a lot of overhead. I suspect the handmade aspect only refers to the gluing of the veneer and the application of finish. With machines providing the engraving, wood burning and actual cut outs to glue up they can probably turn them out quickly. So if its only a couple bucks to make and you can make a dozen or more an hour then it wouldn’t be too hard to turn a good profit.
