Hidden magnets heat shield

I modified the heat shield parts to close the magnet holes. The included 3mf files already have the pause print at the right layer, so they pause, you put in the magnets, and resume the print. I recommend marking the north pole of all magnets, so you don't mess up putting them in. I also recommend still gluing the magnets in, and waiting for the glue to dry before resuming the print. I forgot to glue the magnets on the heat shield, and they rattle inside which can be quite annoying.
