This is a Fibonacci striped watch band for sporting your watch with mathematical style!It fits watches that have a 22mm lug width, and a lug to lug distance of 46.2mm (I designed it to fit a Seiko SNDA65 watch). It fits a wrist size of up to ~180mmI took the same watch band design and made it striped! The number of layers in each stripe corresponds with the fibonacci sequence (1-1-2-3-5-8-13... and so on) My blog post about the design: http://colin-ho.com/3d-printed-fibonacci-watch-band/Makerbot Replicator Settings: Default slicing settings, infill of 100% and 1 (or 2) shells. Follow these instructions to do the dualstrusion gcode generation in ReplicatorG: http://www.makerbot.com/docs/replicator/dualstrusion/Printing this is a bit touchy, since using rafts with the current dualstrusion printing procedure "doesn't work well". Thus keep your eyes out for curling! Took me about 4 tries to get this one to print.Post print assembly:After printing is done, take a small file and carefully smooth out the male and female sides of the watch band clasp until they slide and mate snugly (tight enough to no fall out, loose enough to easily take off)Take a thin metal rod (like a small allen key) and insert it through the spring-bar holes to make sure that the spring bars have no obstructions. Attach the watch one spring bar at a time!
