US Coin Sorter

This is a coin sorter inspired by https://www.thingiverse.com/thing:2189166 It is not, however, a straight remix as I built everything from scratch based on Petland's design.
While I really liked Petland's design there were a couple of things that I didn't like which is why I set out to build my own version. It's not quite as polished as Petland's, but it fits my needs slightly better.

There are a couple things I wanted different for my needs.
1.)Dimes kept slipping back into the quarter tube from the hopper
a.) my design had to prevent that from happening.
2.) My Design had to have tubes that help the correct amount for Bank Coin Roll tubes.
3.) I wanted the tubes to be inter changeable.
a.) if I was sorting/counting less than the four denominations, I wanted to be able to
use multiple tubes for the denominations I was working with.
