Nothing is more embarrassing than getting to the end of a letter and realizing that you don't have a good wax seal for the envelope. With a couple of easy steps, a 3d printer, a kiln, and a spin caster, you can have a signet ring in no time.

Step 1: Design the Ring
Using Sketchup or openScad, or your favorite cad design program design a ring. Below is a question block ring I designed using Sketchup. Also attached is an openScad ring designer I am working on. Whatever you want to design is up to you.
If you use Sketchup, there is a variety of plugins you can get to take your design from .skp to .stl. I found one from the makerbot website, and it worked great.
