This watch-band is designed to snap-together so you can print different colors and swap out links on the fly. This is still a work in progress, the clasp needs a lot of work, and the links need to be beefed up. Nonetheless, I have no trouble wearing it for about a month before having any issues! Designed for the Fossil watch as pictured.Print at 30% infill: Each Watch should include: 2x watch_link_end.stl 1x watch_link_clasp_2.stl 1x watch_link_clasp_1.stl 1x watch_clasp_clip.stl 8x watch_link2.stl To Snap together/apart, get two of the links at a 90 degree angle to each-other, and add a little torsion. You'll notice that the rectangular male 'peg' will match the female side with the notch.
