I made a simplistic key fob (needed one to assist in finding my extra truck key).
You are welcome to use it.
It is ready to score an inner highlight and cut the outside.
All you need to do is take their name, convert it to curves and place it in the inner free space (or a picture - whatever).
When setting it up - Just engrave their name, then remember to score the inner highlight and final process would be cut the outside and hole.
