Maker Coin
Remix combining kwm and enekonontero coins.
Has optional fidget capability. You can customise the text or make your own logo module to get what you need in the center.
Original idea is from here by Maker's Muse:
Works great for customisations in current openSCAD which now has a customiser UI pane to make this easy. Alas customiser is frequently broken here on Thingiverse.
Edit - dimensions, curvature, fidget or not, notches size and depth, and logo text and scale...
