Card box stopper

thingiverse

This nifty stopper prevents cards from spilling over in partially full BCW storage containers. It slides onto the edge and secures with an integrated spring, allowing you to still shut the box if you gently bend it. I find this especially helpful when sorting cards, as it keeps them from constantly tumbling out and creating a mess. I've also created a version that fits snugly over the inside dividers of BCW multi-row storage boxes.
