SD Card Dispenser

Our media center circulates at lot of SD cards to students. A LOT of SD cards. To keep them organized and accessible, and to keep them at a relatively consistent use cycle, I designed this wall-mountable dispenser. Returned cards are dropped in at the top, and a single new card can be pulled from the bottom. The slot at the bottom is tapered to make it easier for your finger to pull the card. I've uploaded three different designs: two-slot, three-slot, and four-slot.
