About this 3D model
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. https://github.com/YoungCatChen/coin-sorter https://creativecommons.org/licenses/by-sa/3.0/
