Expandable Bracelet SO

This is another version of the compact Expandable Bracelet. SO stands for S-shaped forming an O, also see the X version if you prefer. 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.).
Makes a perfect multi-functional gift, just browse the materials and colors.
Cheers!
