After a trip to the bank to deposit some savings from my piggy bank, I received feedback that they need all the coins counted and organized to be accepted. I didn't want to go through the trouble of counting all the coins as they were quite a lot. I did some searching on the internet for models, but none of them were easily adjustable for my needs - coin size and markings for counting.
I didn't want to spent time designing yet another coin counter and I wanted to be compatible for more coin currencies with different sizes. So I spent some time designing a OpenSCAD model, which can be used to generate coin counter for nearly all sorts of circular coins.
Suggested size for the wrap paper is 75mm x 105mm.
