Sandwich medal

My friends and i always make nice sandwiches that we eat at school. We thought it could be funny to make a contest everyday for who had the best sandwich that day. Most of my friends know that i have a 3D printer so they said that i should print a trophy cup, but a cup would be to big, and i came up with the idea to make a medal instead. Every day we choose a new winner, which can be a proud carrier of the sandwich medal!
