(Micro) SD Card Holder with Latch mechanism

I like the "(Micro) SD Card Holder" design in it size and mixture of number of microSD and SD. but using fiction or play with tolerance to hole the card is not ideal.

I then found another design “Slim MicroSD Case” that use “Latch mechanism” to hold the card.

So I did some mixing, and add such latch mechanism for SD card slot too. 

I make some open slot so it is easier to pull the cards out. I also added a full case, but you can still use the same cover in original "(Micro) SD Card Holder" design.

I print my design in 0.1mm layer height and exclusive in tolerance setting.
