Old electric toothbrush becomes an etcher

For a few years I have loyally used Oral-B's disposable Pulsar toothbrushes. But throwing them away when it is time for new bristles seemed extra wasteful. So with a few of them kicking around the bottom drawer of the bathroom to experiment with and a bit of spare time I made one of them into a vibratory etcher.
