When on prusa slicer, add a pause to the print as to allow yourself to situate the magnet into the 3D print. This model utilizes the magnets found in the ring of any iphone. I had this idea when my magnet ring began to suck at its job of sticking to my phone, and when I needed a way to track my players travel across Chult. The hex in middle of tracker fits on the map's hex units.
