When I started the project, I did some research on how big coins were so I would know how big I had to make the organizer.
Then I designed it in inventor and put it into maker-bot. I used a circle as a base because it doesn't have sharp corners.
Finally, I printed it out with the 3-D printer
When making this project, I learned several things. One of them was that you should always increase the size of a hole if it is supposed to hold something specific. I didn't increase the size of the holes enough so coins don't fit into it without an extreme amount of pushing. I also learned how to move a shape in a 2-d sketch in inventor.
