I had a job interview this morning. "Now where are my cuff links? I swear I put them in here!" no matter, I have the power to solve this problem! A simple square cuff-link with a circular indent in the center. I had best luck printing as shown in the first image, including support material. You can experiment to find what works best for you. Included are a 5/8" and a 1/2" version, depending on the look you want. I can be seen in the picture with the 5/8" model. They made a great impression at the interview, and had people fascinated!
