3x5 Index Card File Box
An open-top desk file box for standard 3x5 in (76 x 127 mm) index cards. The cards stand on their long edge, and the box holds about 77 mm of stock, roughly 400 cards. The 132 mm inner width leaves 2.5 mm of side clearance, and a 44 mm U-shaped notch in the front wall lets you thumb through the deck. The walls are 2.4 mm thick, the outside is 137 x 82 x 52 mm and the box needs no supports.
Quarter-Sheet Sandpaper Six-Grit File
A bench file box for standard quarter-sheet sandpaper (4.5 x 5.5 in, 114 x 140 mm, cut from a 9 x 11 in sheet). It has six 8 mm grit slots with 146 mm of internal width and a sloped front-to-back stair profile 20–45 mm tall. A deep centre thumb notch through every divider lets you pinch a single sheet out instead of digging through a curled-up pile. Overall size is 151 x 61 x 45 mm.
