See a demonstration of the card here:
And here is a video that shows you how to make your own:
Step 1: Download the design files
If you have any problems with the Instructables attachments the files are also available here: http://www.thingiverse.com/thing:16735
Step 2: Required tools and materials
- 16 pennies (or other similarly sized coins)
- Some tape
- At least one 'jumbo' sized paper clip
- Some cardboard or thick paper
The tools you need are:
- A sharp knife
- A printer or other method to transfer the design to the material.
Step 3: Transfer the design
The easiest way to transfer the design would be to just print it directly on the cardboard, but most printers cannot handle that thick of a material, so here are some potential alternatives.
You could print on a normal piece of paper and glue it to the cardboard.
You could cut it out from the normal paper and trace the design onto the cardboard.
Or you could use some kind of trace paper or pen with heavy bleed to trace the design onto the cardboard through the paper.
One thing that you want to check in all cases is that the design is not being scaled to a different size when you are printing it. The overall design should be 3.5" by 4"
