compact travel friendly SD/microSD card holder

I was planning a 2 week trip out of the country, when i realized i would need more than one SD card with me for my cameras, but not more than 4 extras. and so, this SD card protector/organizer was born. it fits: 2x regular SD cards 2x MicroSD /TF cards or 2x MicroSD cards /TF cards with SD adapter 2x Full size SD cards when designing this, i had travel, and ease of use in mind, so i opted to go for a no-lid solution. where the contacts of the SD cards would be covered, and the cards would stay in place, as well as not take up too much extra space. i wound up with a pill -like shape on the back, to hopefully increase pocketability Originally i was planning to make a slide on lid for it, to encapsulate all the SD cards, and give further protection. but as that would decrease hot-swappability. i ultimately decided against it. feel free to remix this design, or do with it whatever you want. have a nice day
