Quarter Holder/Dispenser with Travel Ring

This is my first original design from scratch. Opinions?

A simple and efficient travel sized container for holding quarters, it's a Piggy-Bank-on-the-Go! Easy to add or take away quarters, can be attached to bags or belt.
[Other coin sizes coming soon]

Parts and Functions: 3

-Main body tube: Holds quarters, with 4 "peep holes" to quickly see how many you have left (4/4, 3/4, 2/4, 1/4). Has a hole on the bottom big enough for a finger to push the coins up from the bottom if there isn't enough coins left to just take it from the top, but small enough that quarters won't fall out. [currently designing v.2. where the hole is not needed where there is a little slider that goes up and down]

-Screw on cap
A simple lid with a slit on the top so you don't have to unscrew the cap every time the cashier gives you one or two quarters to put them in. It's small enough that it is very unlikely for any quarters to fall out when shaken.

-Travel Ring
I put this in there so that I can attach the ring to the top of the inside of my book bag so that it is easy to reach, and easy to take out of the ring, just slide it in or out. You can also attach a small piece of cord or string to it and attach it to your belt.

I printed mine with 100 Microns with PLA with my Da Vinci Jr. 1.0 with 10% infill.

If there any suggestions or problems you come across while using it, I'd appreciate it and I'd include a fix for it in v.2.
