Dollar bill holder

This is a dollar bill holder I designed in TinkerCAD. It was a request from a co-worker to store her money through out the year. The box can be sealed so it cannot be accessed without breaking, or 1/4 in dowels can be put into the base and screwed down with #6 1/2 inch screws in from the base's bottom and the lid to keep it closed and allow access for those among us who have discipline.

Internal height is approx. 61mm, allowing for about 600 bills to be held inside. There is also a press that rest on top of the bills to allow the bills to lay flat.
