There are several levels of personalization available, depending on how much effort you want to put in. The easiest is to scale the file to fit your wrist (the current design has a circumference of 17.1cm with two pieces). Any number can be joined to form a larger circle. By adding M1 commands to the Gcode you can switch colors at different heights to highlight certain features (as shown). And finally, you can modify the OpenSCAD file to turn your own design into a segmented, flexible bracelet.
