Hexagon Running Medal Display

I was commissioned to make some hexagon displays for running medals.  I did not want any seams on the face so I designed it using magnets to hold the lid on.  I used 6mm magnets (https://www.amazon.com/dp/B07873ZCY4?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1) for both the lid and base.  I used 4 in each lid and base but the lid is hard to get off so 2 in each would probable be enough unless your medal is really heavy.  The magnets are pressed into the base and are recessed so the lid magnets can slot in and prevent the lid from sliding off.  The magnets in the lid are glued in.
