Board game insert card spacer

thingiverse

This caps off a card well in a board game insert so that the cards don't spill out when you store or carry the game upright. Change the x and y dimensions to match the card size and the z dimension to about a half inch (or less if there isn't that much space between the top of the deck and the edge of the insert). With the board and/or game lid in place, the cap will hold the cards in place.
