PSA card box

A parametric storage box with lid for PSA graded trading card slabs, designed to hold 1–60 cards standing on their long edge. The box features adjustable slab dimensions (default ~80×135×8 mm), wall thickness, and clearance; the lid includes an inset lip-and-rim joint for a slip fit, a curved handle arch for carrying, and a pivoting latch that hooks under a catch on the front. All parts are optimized for FDM 3D printing in PLA with divider ribs to organize and protect the card stack.
