after this prints, you need 8 springs ( .5 inch diameter, and 2.5 inches tall). place the springs in the designated spots, and then put the rectangle piece on top. now, load up your business cards, then set the lid on top. now, all you have to do is simply slide a card out through the designated spot in the top, and then it will automatically reload.  you could also print the springs after modeling them in fusion 360 to fit the required size.
