Adafruit hs provided an easy step by step tutorial for people to make their own customized 3D printed graphics they can affix to hats and other accessories. Video tutorials provide instruction for using 123D to create the design (or you can download and change their own original graphics files). Then, preferably using Ninjaflex's Semi Flex filament, you can print out your graphic letters and affix them to any accessory: hats, bags, backpacks, the back pockets of jeans.
