Step 3Cut card to shape

Next, use your marker and creative license (you have your license, right?) to design the shape of your belt cutter and channel opening. Since you'll be covering the plastic card you can draw willy-nilly to find that perfect shape. I chose a minimalist design but you could go for whatever shape and size you wanted.
Position the small blade you just snapped over your design to ensure that you have enough room on the card. I recommend maybe going a little larger than you need as sanding the plastic is easy, the metal not so much.

Once you are satisfied with your design cut the card into two blanks, mine measure 2cm x 5.3cm (0.8" x 2") each. Use your hobby knife to carefully rough out the inner channel, this channel is what will guide the seat belt to the blade.
