3x5 Index Card Desk Stand
A desk stand for standard 3x5 in (76 x 127 mm) index cards, used for to-do lists, flashcards or recipe cards. The front slot is 131 mm wide and about 14 mm deep, so it holds a stack of roughly 60 cards leaned back 15° where you can read them. A 24 mm deep pocket at the back takes the cards you're finished with. The stand measures 137 x 70 x 61 mm, and the thin-wall plate-and-cheek build keeps the plastic volume down.
