They might not be the strongest magnets or the strongest adhesives, but I've used them to make some 3D printed fridge magnets and they aren't dropped yet. The adhesive so far will stick to both ABS and PETG, although the magnets will take some time to flatten out and fully adhere after curling. A 3D print I had held four magnets and could hold about six sheets of paper in the fridge. The other only had room for a section and a half and held about three sheets. The magnets can also be easily cut with scissors.
