Playing/Collection Cards Book Case (Parametric)

A parametric playing/collection cards case that closes on itself like a book.

• Print-in-place design (no assembly required).

• No excessive overhangs (max. 35° on conical hinge pins and max. 45° hinge knuckles).

• Easy multi-color printing with a minimum number of filament swaps.

• Optional magnet holds (recommended if you plan to store the case vertically).

• Last-card cutout , picker aid.

• Cover lid to prevent the first card from slipping out too easily.

This model is fully parametric. Download the Fusion 360 design file, open it, then go to Solid → Modify → Change Parameters to customize any value, so you can fit any card and deck size you like. Some values may require further adjustments to the model.

Parameter Default Value Description
card_width 64 mm Width of a single card
card_height 89 mm Height of a single card
card_clearance 2 mm Extra clearance around each card (avoids a “too perfect” fit)
deck_height 25 mm Total height of the stacked cards (you may need to change the picker_* parameters if you change this to high or low values).
deck_clearance 5 mm Extra clearance above the deck (ensures the cover closes smoothly, but may allow to the cards to move inside the case)
cover_thickness 5 mm Thickness of the cover (affects hinge dimensions)
cover_padding 5 mm Padding between the cover edges and the cards box
magnet_* Various holes/tolerances for magnet inserts (may require adjustments to cover parameters)

The model includes two magnet holes to help keep the case closed:

• Cover: Ø 3 mm x 1 mm

• Case: Ø 3 mm x 2 mm
