Trying to find aftermarket cases for various systems

Im trying to find good aftermarket/replacement shells/cases for various systems (mostly portables), as over the course of time (and various other reasons), the shells of my systems have suffered.
I got a chinese shell for my original NDS but, as expected to be honest, quality is crap (i had to frankenstein it with the black bottom of the original shell because the new one didnt fit at all, and the "lens" that goes over the top screen got scratched by simply looking at it).
While plain shells would be good already, something more fancy (like metal or maybe even carbon fiber) would be gooder
If you know where to get stuff like this id love to get some pointers (hard mode: needs to ship to europe/germany)

 

There are replacement shells available for the 3DS (XL, NEW etc.) that are basically the same as the originals. They can be found in the usual places (ebay, aliexpress).
