After seeing FischFuss' coin organizer design, I had the idea to recreate it in OpenSCAD in order to allow customization for other coins. This here model is pre-set for Romanian coins (_10 bani_ and _50 bani_), but it should work for other coins by adjusting the diameter and thickness variables. Yes, I know there are some hardcoded parts (like the border), but this is where you have the chance to learn OpenSCAD :)
