Pebble Watchband
Replaced by http://www.thingiverse.com/thing:627447 which has the entire band.
The band on my Pebble split, so I printed a replacement.
Included is the STL file, which matches the Pebble band, and the OpenSCAD source file in case anyone wants to tweak it.
Note that I only modeled the strap that broke. I kinda like the contrast between the black and yellow so I didn't print a replacement for the other strap. The strap that broke is the more likely one to break for others, so hopefully it's still useful. Or it'll inspire someone do do a few more lines of OpenSCAD coding to model the other strap.
UPDATE: I added the rest of the band at http://www.thingiverse.com/thing:627447 .
