Push Pin Magnet

I wanted to remix the initial design to have something that can be customized to any magnet size. Applies only for disc magnets with a limited height. I've created a remix for higher magnets.

I've set a tolerance (margin) to leave some space around the magnet, in my case, leaving it to 0 the magnet is well blocked in the socket (In some cases the magnet required some glue to stay still). Negative values are also supported.
