This is the base model for a bracelet with a fixed fastening. Included is the .blend file. If you intend to, you can use that file in Blender to write text onto it. Other CADs should work fine, included in the .stl. 

If you add text, the model has worked fine when changing the color for the last layer. Right now, the bottom layer is printed so it flexes around your wrist easier. However, this print orientation might not be that durable (durability on the 10 cent jewelry is probably what you're after, I'm so sorry). 

If you have any (appropriate) requests, leave them in a review and perhaps I can get it done for you :]
