3D printers can do anything. I wanted to make a present for a friend, and she loves earrings, so I decided on some fancy ones I designed and was able to 3D printed! They are a great gift! This instructable covers the steps to design one with a 3D modeling program, but I will also discuss several ways to make them unique. Anyways they look great and are very lightweight. I think the natural PLA filament type looks the best, it's a little tough to tell from the pictures but they reflect a lot of light. I would also like to thank my sister for modeling them. I was fortunate enough to be able to use a Makerbot Replicator 2 to build them, and you can see a time lapse of it below.
A basic knowledge of the 3D modelling program you will use is highly recommended. Watching whatever tutorials/examples they offer will probably be plenty. I used Autodesk Inventor 2013.
The first thing that needs to be chosen is the base shape for your earring. I used a circle to keep things simple. To start make a 2D sketch of your base shape in your 3D CAD program. See my picture for help.
