About this 3D model

It holds the standard US coins: Quarters, Dimes, Nickels, Pennies. It is spring loaded for easy and precise removal and fits nicely in a cup holder such as in a car. That's where I use mine and I love it. Print is very simple. If you don't have rubber (which everyone should If they can afford a 3D Printer) then you can print the holder (and if you want the lid too) and use it as a standard coin organizer If anyone has any ideas on how to improve the design I would love to hear them and hopefully integrate them so let me know.
