For my wedding, I wanted to have cufflinks shaped like my home state of Minnesota, but I couldn’t find them anywhere. Consequently, I decided to design them myself in Rhinoceros CAD and 3D print them in pure silver. My wedding guests loved them so I decided they might be worth selling. I used the same template to make the rest of the US states as well as several other cities, countries and territories, then opened 3D printed jewelry shops on Shapeways and Etsy. Hundreds of pairs sold.
