Soft corner for shelf

A shelf in my garage is head height and I have always been wary of hitting my head on it. When printed in TPU this soft corner piece provides protection whilst not hindering the ability to slide heavy things on and off the edge of the shelf. It can be fixed into place with two screws that are set far enough apart from each other to not interfere with each other.
