Potential tool hackery for my friends over the land of boffer crafting.
An easy, useful, inexpensive, and delightful improvisation from model-maker and Instructables user WiredWebbo101, who needed a handy tool to sand primer in some hard-to-reach places on his models. So he modified a disposable electric toothbrush by flattening and pointing the head and attaching a dart-shaped piece of sandpaper. Wonderful!
