About this 3D model
I ran across Nervous Systems [Kinematics@Home](http://n-e-r-v-o-u-s.com/kinematicsHome/) app, based on their [Kinematics](http://n-e-r-v-o-u-s.com/blog/?p=4467) post. This is a bracelet I made for my wife based on that system. Can't believe how well it turned out! You can download and print this thing, or go to the above link and make your own.
