Here, the XS stands for X-shaped Slide-able! This is the Ultimate expandable structure bracelet, look in the cover image for possible configurations. This version is light and uses less material than other models but is also more fragile. Now available in Hard/Flexible and Frosted Detail plastics. I suggest Shapeways purchases SLS metal printers to be able to produce Interlocking mechanisms like this one in a One-Step simple process with Precious Metals (semi, etc.).
Also look for other versions and designs in this store.
These designs were created by BDan operating in the Sensorica FabLab and 5% of revenues go to support the Infrastructure. :)
NOTE:this product is no longer ''First to try''.
