Summary

An automatic coin sorter for many currencies. See also http://youtu.be/7F2fIF9PNBk for a short demo video.

To store a coin, you may release a coin from the rightmost top, and it will slide down the hill and go into the right tube. To get a coin, you may pull the whole rack out and take out any coin.

Versions:

• US dollar (USD)
• Euro (EUR)
• Swiss franc (CHF)
• Canadian dollar (CAD)
• Thai Baht (THB)
• Customizable .scad file

Don't hesitate to download the three parts for the currency that you use and print them out. You can also find the .scad source file, which you may customize to fit your own currency set. The source is also available at GitHub.
