Jack O'Lantern Magnet snap faces

I didn't like the way the clips sagged and i tried printing them in different shapes with now resolve. So i threw them in tinkercad (which i suck at digital design) and tried to fill in holes and make holes to fit 6mm x 3mm magnets i have from amazon. Magnets actually measure 6.47x3.15. Printing on a bambu x1 carbon. I also increased the height of the body and faces by 10% to help with magnet size. This still my trial and error. Posting this after my 2nd attempt. ANY help is apperciated.
