Battery Cover Wrench

This is a simple wrench designed to remove the battery cover of one of the products I sell. They made the covers very sturdy and no longer can you use your fingers to remove it. So instead of grabbing a pair of plyers or something that will mar the finish, you can print your own wrench. Enjoy. https://youtu.be/dXiClWtM5xg
