This is the flexible name bracelet (http://www.thingiverse.com/thing:46735) in full version. You need to use specific slicing settings to print this hollow and obtain a bracelet, see Instructions.

This is a full render, so to print it as a bracelet, you must give specific instructions to the slicer. I present those for Cura here:

In Cura, go to menu Expert->expert settings. There do:

• Solid infill top: off
• Solid infill bottom: off
  In the Basic settings doL
• fill density: 0 %
• Shell thickness: set 1x or 2x your nozzle thickness, depending how strong you want the bracelet. I have good results with 0.4mm (my nozzle)
• set layer height sufficiently precise, eg 0.15 mm, and if layers are not nicely connected, set your flow rate a bit higher than 1, eg 103%

Success!
