coin storage card (ver Korean coins)
thingiverse
It's designed to store coins in a bifold wallet, tailored to Korean coin specifications, but if your country's coins are larger than 26mm and thicker than 2mm, you can still use it. When printing, check the flexibility of your bed; only one or two layers will stick. If that doesn't work, print out the Coin Card _ No Bottom.stl file and add paper to complete it. I have a few tweaks in mind, but they'll take some time to update. P.S. There are similar designs available, like this Swiss coin version: https://www.thingiverse.com/thing:570094. If you're customizing for your country's coins, I recommend keeping the total thickness under 2mm.
