We heard of patient recently who turned an electric toothbrush into a $5 mini power sander. This patient got the idea from YouTube. First you cut the bristles off an Oral-B electric toothbrush. Then you hot-glue a small plastic circle to the head and attached self-adhesive sandpaper. The sander can make small cuts or grind fine details on plastic models or miniatures. This fits the bill for a hobbyist ….and it’s a great deal!
