Universal Magnetic Vise Jaw Protector - without profile

I use the magnetic vise jaw protectors as made by CBiker (https://www.thingiverse.com/thing:941380) quite frequently to clamp round items in my vise or to protect items from markings from the metal vise jaws. However sometimes the profiles in there are impractical and hence I made a flat version. Just glue four 8x3 mm Neodymium magnets in the recesses and - after drying :-) - snap the protectors on your vice.
