Update 3.5.2014: fixed the issue with the excessive material in the inner circle

Open it in the customizer. As bracelet stretches, give inner radius so as to sit nicely on your wrist. Set outer radius, set height, and set the text you want on the bracelet, eg a telephone number where you can be reached!.

The text can be in relief, or as holes. When printing relief, make sure you print with 100% infill. Holes still must be tested on a printer, I assume you should print thick and slow so as to not jump over the holes too fast.

It is important that you give the nozzle diameter of your 3D printer, as this is what will make sure your bracelet does not break easily. The thickness is one nozzle diameter, if you want the bracelet thicker, set nozzle to 2 or 3 times your real nozzle diameter
