I recently finished my first 3âDâprinted wallet and, after tweaking its dimensions, discovered that a halfâmillimeter clearance was needed between the credit cards and the tray to avoid warping and misâfitâan adjustment that automatically recalibrated the model via Geometry Nodes. Though I initially forgot horizontal clearance, the vertical gap worked because the plastic corners can warp slightly when printed. The walletâs design uses extruded holes for card slots and a rail or hinge system (similar to a door hinge) to join compartments, all generated procedurally so the final belt kit can be printed in separate parts that assemble with screws. This approach not only solves fit issues but also opens up possibilities for a fully procedural âSuperhero Beltâ kit ready for 3âD printing and assembly.
