2 part holder for deck of cards.  Extra height to account for plastic playing cards.

top and bottom interlock to contain cards, used separately to hold “draw” and “discard” piles.

Lid art designed suited to using cards for workouts.

Prints with colour change after first 2 layers, then back after 1 or 2 layers.   **DO NOT USE SUPPORTS** the warning is due to the bridging (for the colour change), which any printer should be able to do without any issue, as they are all short bridges.

If you want more retention, you can heat and slightly bend the lid so it arches slightly, which will bring the legs in.  A little goes a long way.
