I used the following 1/4" magnets press-fit into the holes: https://www.amazon.com/gp/product/B07CVPC3YJ Depending on how your 3d printer prints, the magnets may fit too loosely in the holes and can be secured with a drop of crazy glue. If the magnets are too large for the holes, heat the magnets up with a lighter and then (carefully) press them.
