I want to have money clip that could hold the credit cards or ID similar to the one I had, as well as some decoration on the money clip that reflects itself as the money clip better. And I want the money clip to be 3D Printable and could be made out of various materials, for example, plastic, brass, silver, stainless steel, etc.
Unfortunately, it really not easy to find such a money clip. So I decided to design my own money clip/card holder myself. And the result are, Fortune Frog Money Clip, as shown in picture 1 and 2.
Provided is the first version of the "Fortune Frog" money clip STL file.
Step 1: Design Concepts & Processes
In the western civilization, credit card is also used as a money. So I added the credit card holder as an element of my money clip.
Why the frog, and ancient Chinese coin?
While I did some research on money clip, the word money frog, a popular Chinese symbol for prosperity, show up on my search list as well. Also in some part of Japan, especially in Yamanashi Perfecture, some people believe that carrying the image of the frog as a good luck charm in your wallet will help bringing the money or prosperity back after you spending it.
For the ancient Chinese coin, which contains the square shape in the middle and round shape on the edge. These characteristics bear the meanings. The square in the middle representing the energy on earth, and the round shape representing the energy from heaven. So the ancient Chinese coin is believed to "move" the energy of fortune from heaven to earth or the person to get hold of the coin. And it is believed that if you tie these three coins together and put them in your wallet, they would bring you prosperity.
So I looked into it, and found that this is a good idea to add these elements into my money clip design.
I started the process by looking for the standard size of the credit card. I used the ISO/IEC 7801 (ID-1) standard size of credit card or ID card, which is 85.60 mm Long x 53.98 mm Wide, with a nominal Thickness of 0.76mm, and the round corner of radius of 2.88mm to 3.48mm.
I drew the actual credit card on my sketch book. Then I made some sketches of the frog that holding the coin with its mouth, and its hands. And created the actual drawing of my money clip.
I also drew the side view of the money clip design. So I knew roughly what would be the thickness of the money clip. I decided to have only two holder for credit card/ID because I do not want the money clip to be too thick to put it in my pocket.
The outer cover of the credit card/ID holder has the frog with the coin on its mouth. On the other cover of the credit card holder, there is only the frog with the void circle.
And on the money clipper, I designed it to be a frog with no arms holding a thick smaller coin in it mouth. The reason I did not added the arms of the frog because, I was afraid that the fragile articulate arms will be broken easily, while we insert or remove the banknote.
This thick coin extruded down almost touch the surface of the side of the credit card holder. The function of this thick coin is to press the layer of banknotes tightly in place.
