Has anyone done this? I'd like to have two 4x4 plastic pieces that are 1/2" thick be able to attract and pull apart. I read that doing this will reduce the pull force by approximately 45%. I'm also wondering how to do this as I've never worked with plastics. Maybe use a router to create a cavity and seal it somehow? Or perhaps make a mold and pour plastic on the magnet? Perhaps that is a question for another forum but I appreciate any thoughts.
