In this project, I made a lot of ID card holders: some are made of both hard and soft plastic, some are made of just soft plastic. The soft card holder worked really well, the hardness of the holder is perfect and it is much easier to make than the hard holder. One obstacle I had is cutting plastic cake, so after a few prototypes, I decided to use laser cut. I created a few different soft holders, each is better than the one before. The first one had spiky edges, the second and third prototype are broken and are too small for the lunch card to fit. The final prototype has a stronger cover, perfect sized, and the edges are straight.
