Ender 3 Magnetic Tool Holder

Loved @DaVinci2000's design so I decided to remix it slightly. Made it larger and to accept 18mm Dia magnets. Magnetic holder for spatula or other metal tools, like Allen keys, wrench, tweezers, etc. It fits 18 mm neodymium magnets, up to 4 mm thickness secured with epoxy glue. 2 mm is enough to keep spatula firmly in place.
