Card Deck Draw/Discard Cradle

I play tabletop games that often use large stacks of playing cards during play. To preserve my cards I've put them in sleeves that make them slippery which causes the card stacks to sometimes fall over and scatter all over the table. So, I designed this cradle to hold my draw and discard stacks. The cradles are ~71mm wide and ~100mm deep. Standard cards in sleeves fit great. The floor of the cradle is sloped so cards stay in the cradle on their own.
