Shell for 4 button keyless fob?
 

Does anybody know of a company that makes an aftermarket shell for the 4 button "keyless" fob that came with some FRS (in my case 10 Series) and BRZs? I'm talking about the rectangular fob with the key stored internally, not the diamond shaped fob that seems to be far more common. Preferably, it would have a flip out key function, but I'm open to options.

Odd google couldn't help?
Found a few, from leather to carbon fiber looking one.

For the rectangular 4 button fob, not the one with the external key? if so, a link would be much appreciated since I've spent hours on google and have yet to find a match for my particular fob (even searching using other makes and models that use an identical fob)

@Stang70Fastback was making a 3D printed shell for these. http://www.ft86club.com/forums/showthread.php?t=129120
