These incredible magnets are great for anything that you would use Velcro, brass fasteners, hinges, pins, etc. My clients range from craft companies to hobbyists to painters to carpenters to purse makers. These little magnets have MILLIONS of applications.
8x3 countersunk is a common Ender 3 enclosure latch size. Several Printables enclosure designs use 8x3 rings to hold acrylic doors with M3 flat-head screws. RC battery tray covers and pit-mat tool holders use the same size against a steel plate.
WARNING! These magnets should be kept away from any animal or human who might try and eat them, they have the potential to separate and pinch intestines causing serious and life threatening complications.
BRITTLE! These magnets are more brittle than glass, please make sure you don't let them slam into each other or drop onto the floor, they WILL break and I will be sad for you.
Let me know if you have any questions!
