This file will help you create a acrylic key fob with leather strap. You will need acrylic or wood Key Ring Rivet Leather
Place a piece of acrylic or wood in your machine that it big enough to make your fob.
You will need a piece of leather or leatherette at least 100m x 15mm I would recommend just abit bigger.
Once you have your leather cut out, run the strap through the slot of the key fob, then fold at the top and attach a key-ring, then push your rivet through all three holes when lined up. Set your rivet.
