A friend of mine just had their first baby and I thought to myself “what better way to teach them about the most important things in life by turning trading cards into a baby toy?

After the two halves are finished printing, the latching piece has a sacrificial support layer that can be removed or cut to allow it to move more freely. It can also be left for a more secure fit. Then just glue the two halves together and add your favorite card!

The slot is 101.8mm x 77mm x 2mm to hold a standard hard toploader. The toploader should be inserted with the bottom facing out so that the more rigid base prevents it from sliding out.
