Multi-deck Parametric Card Box with Snap-on Lid

Fusion 360: Change parameters for desired card dimensions and stack height. Add about 2 mm to each to allow room for usability. Height above 30mm not recommended due to flex (thicker walls and bottom may help). Set InstancesX parameter for 1-8 decks. Set InstancesY parameter to 2 for a second row of decks. If model corrupts, try Compute All (Ctrl+B). Slicer: No solid top and bottom layers. Use cubic 21% (or similar strength) infill. To see through lid better, increase extrusion width (0.88mm) and use a 2D pattern like triangles. About 6-9 perimeters for rigidity. 2023/11/05 - Fixed bug in model. 2023/11/20 - Added second row and independent top/bottom cutout lengths allowing for verticals. 2023/11/30 - Removed pattern from workflow for compute stability. 2023/12/06 - Added parameter to allow room for a manual on the top. 2024/02/17 - Added parameters for top and bottom thickness. 2025/09/04 - Better scaling for smaller cards/tiles.
