Need to pull a big-ass dent out of an appliance before moving? That's the weirdly specific use I had for the simplest 3D design you've ever seen anyone publish. Print it with a lot of walls and high infill, or you'll be reprinting it just to get the vice-grips on. Secure it with hot glue in the middle of the dent and pray the paint sticks harder to metal than glue. So go on, park blocking someone else's driveway. Dent's can always be pulled...
