7 wonders duel coins holder for custom insert

I did a coins holder that fits in the hole of the insert for sleeved cards (https://www.thingiverse.com/thing:2892746/makes). I was inspired by https://www.thingiverse.com/thing:4655718 (which has wrong measures according to comments).
I didn't manage to make all 3 coins fit, so one of them has to be passed on to the pile of 6 coins. Besides that, it fit pretty nicely on the modded insert. If one trims it 1 or 2mm on each of the short sides, it also fits in the original insert.
I think the hole for picking it up could be improved by expanding the hole sideways, but it works reasonably as it is (for my fingers at least).
