Ender 3 Mounted SD Card Holder

This is a little accessory I made for my Ender 3 to hold all my micro SD cards near by the printer. There's two versions, one that I've printed, as shown in the picture. The 2nd version is when I went back after the first print, and changed the little cubby on the bottom into 10 more slots for micro SDs instead, as well as widened the mouth holes for all 20 micro SD and the 1 SD card slots, because it was quite a tight fit that I prefered a bit looser.
