Micro SD extension card holder for full graphics A6 display LCD 12864 case

I spent half a day printing this display case (from witch I made this "remix") and I asked me "why is it so big?". I couldn't find any answer except "for beauty reasons"...
Anyway, I thought, what can I make meaningful with the available, unused space? An SD card holder would be great!

And so there is it! Right now it is again only an "add-on" like my reset protection for this case here: https://www.thingiverse.com/thing:2939310
But I don't want (yet) to redesign the case to make the holes
