About this 3D model
The Fitbit Flex is a wonderful movement monitor, a tiny device that captures motion during the day so you know how much you moved, how you slept, and so on. You wear it in a wristband which looks great, but is constructed of three pieces that are glued together. Mine came unglued, so I designed and printed a replacement. UPDATED: Added a box for carring / presenting the FitBit band. Made more clearance for the ends to link The wristband links are joined by profhankd's printable hinge.
