Pretty straightforward remix to transform the original Pokeball TCG case into a Love Ball.
Print everything and assemble with adhesive of choice.
There are slots available in the base ring (under the release “button”) and top insert for 10x2mm magnets to help hold the case closed, just make sure you align the magnet's pole correctly.
Holds about 150 unsleeved cards or 75 cards in Dragon Shield “Perfect Fit” sleeves.
