I've few USB flash drives, SD cards and micro SD cards laying around, but I don't want to print large holder, because it's simply loss of material for me. I wanted to make something original, so I've decided to make "staircase" holder, which performs really well!

This model can hold :

• 2 big USB drives of 4 smaller USB drives
• 2 SD cards (or microSD to SD reduction)
• 6 microSD cards
  at once!

I think that this comes really handy if you have 3D printer and you are using microSD card + reduction to print!
