I designed this clip for the Misfit Flash after the one that came with the tracker broke. I looked around online and could only find replacements for the Misfit Shine. This should probably be printed with a brim. Slide the Misfit in from the side. The clip seems to have a good hold on the device - I haven't had it fall out after more than a month of daily use. Edit 9/4/2015 - added a "watch band" version. I haven't printed it and do not have a watch band that works with it. If it needs adjustments, let me know.
