When printing, print as a 2 layer shell. no infill...See slicer settings in the Instructions tab. I'm using NinjaFlex flexible elastomeric filament, so they are very tough, flexible, and always return to shape. The flex filament I'm using is available here: http://www.fennerdrives.com/3d This material is very easy to print with. I'm working on lots of other flexible bracelet designs... If there's interest, I'll post them here.
