I created the PCB and I solder the surface mount LED's on them. I wanted an easier way to mount them, this fills the bill. I also wanted the back to have no contacts so it could be glued down and still insulated from the shell.
Here's the Gerber file for upload to OSHPark for PCB blanks if you would like to make some. Ignore the error about the missing solder mask on the bottom, that's intentional, there's nothing there!
